-govaluate
-====
-
-This library contains quite a lot of functionality, this document is meant to be formal documentation on the operators and features of it.
-Some of this documentation may duplicate what's in README.md, but should never conflict.
-
-# Types
-
-This library only officially deals with four types; `float64`, `bool`, `string`, and arrays.
-
-All numeric literals, with or without a radix, will be converted to `float64` for evaluation. For instance; in practice, there is no difference between the literals "1.0" and "1", they both end up as `float64`. This matters to users because if you intend to return numeric values from your expressions, then the returned value will be `float64`, not any other numeric type.
-
-Any string _literal_ (not parameter) which is interpretable as a date will be converted to a `float64` representation of that date's unix time. Any `time.Time` parameters will not be operable with these date literals; such parameters will need to use the `time.Time.Unix()` method to get a numeric representation.
-
-Arrays are untyped, and can be mixed-type. Internally they're all just `interface{}`. Only two operators can interact with arrays, `IN` and `,`. All other operators will refuse to operate on arrays.
-
-# Operators
-
-## Modifiers
-
-### Addition, concatenation `+`
-
-If either left or right sides of the `+` operator are a `string`, then this operator will perform string concatenation and return that result. If neither are string, then both must be numeric, and this will return a numeric result.
-
-Any other case is invalid.
-
-### Arithmetic `-` `*` `/` `**` `%`
-
-`**` refers to "take to the power of". For instance, `3 ** 4` == 81.
-
-* _Left side_: numeric
-* _Right side_: numeric
-* _Returns_: numeric
-
-### Bitwise shifts, masks `>>` `<<` `|` `&` `^`
-
-All of these operators convert their `float64` left and right sides to `int64`, perform their operation, and then convert back.
-Given how this library assumes numeric are represented (as `float64`), it is unlikely that this behavior will change, even though it may cause havoc with extremely large or small numbers.
-
-* _Left side_: numeric
-* _Right side_: numeric
-* _Returns_: numeric
-
-### Negation `-`
-
-Prefix only. This can never have a left-hand value.
-
-* _Right side_: numeric
-* _Returns_: numeric
-
-### Inversion `!`
-
-Prefix only. This can never have a left-hand value.
-
-* _Right side_: bool
-* _Returns_: bool
-
-### Bitwise NOT `~`
-
-Prefix only. This can never have a left-hand value.
-
-* _Right side_: numeric
-* _Returns_: numeric
-
-## Logical Operators
-
-For all logical operators, this library will short-circuit the operation if the left-hand side is sufficient to determine what to do. For instance, `true || expensiveOperation()` will not actually call `expensiveOperation()`, since it knows the left-hand side is `true`.
-
-### Logical AND/OR `&&` `||`
-
-* _Left side_: bool
-* _Right side_: bool
-* _Returns_: bool
-
-### Ternary true `?`
-
-Checks if the left side is `true`. If so, returns the right side. If the left side is `false`, returns `nil`.
-In practice, this is commonly used with the other ternary operator.
-
-* _Left side_: bool
-* _Right side_: Any type.
-* _Returns_: Right side or `nil`
-
-### Ternary false `:`
-
-Checks if the left side is `nil`. If so, returns the right side. If the left side is non-nil, returns the left side.
-In practice, this is commonly used with the other ternary operator.
-
-* _Left side_: Any type.
-* _Right side_: Any type.
-* _Returns_: Right side or `nil`
-
-### Null coalescence `??`
-
-Similar to the C# operator. If the left value is non-nil, it returns that. If not, then the right-value is returned.
-
-* _Left side_: Any type.
-* _Right side_: Any type.
-* _Returns_: No specific type - whichever is passed to it.
-
-## Comparators
-
-### Numeric/lexicographic comparators `>` `<` `>=` `<=`
-
-If both sides are numeric, this returns the usual greater/lesser behavior that would be expected.
-If both sides are string, this returns the lexicographic comparison of the strings. This uses Go's standard lexicographic compare.
-
-* _Accepts_: Left and right side must either be both string, or both numeric.
-* _Returns_: bool
-
-### Regex comparators `=~` `!~`
-
-These use go's standard `regexp` flavor of regex. The left side is expected to be the candidate string, the right side is the pattern. `=~` returns whether or not the candidate string matches the regex pattern given on the right. `!~` is the inverted version of the same logic.
-
-* _Left side_: string
-* _Right side_: string
-* _Returns_: bool
-
-## Arrays
-
-### Separator `,`
-
-The separator, always paired with parenthesis, creates arrays. It must always have both a left and right-hand value, so for instance `(, 0)` and `(0,)` are invalid uses of it.
-
-Again, this should always be used with parenthesis; like `(1, 2, 3, 4)`.
-
-### Membership `IN`
-
-The only operator with a text name, this operator checks the right-hand side array to see if it contains a value that is equal to the left-side value.
-Equality is determined by the use of the `==` operator, and this library doesn't check types between the values. Any two values, when cast to `interface{}`, and can still be checked for equality with `==` will act as expected.
-
-Note that you can use a parameter for the array, but it must be an `[]interface{}`.
-
-* _Left side_: Any type.
-* _Right side_: array
-* _Returns_: bool
-
-# Parameters
-
-Parameters must be passed in every time the expression is evaluated. Parameters can be of any type, but will not cause errors unless actually used in an erroneous way. There is no difference in behavior for any of the above operators for parameters - they are type checked when used.
-
-All `int` and `float` values of any width will be converted to `float64` before use.
-
-At no point is the parameter structure, or any value thereof, modified by this library.
-
-## Alternates to maps
-
-The default form of parameters as a map may not serve your use case. You may have parameters in some other structure, you may want to change the no-parameter-found behavior, or maybe even just have some debugging print statements invoked when a parameter is accessed.
-
-To do this, define a type that implements the `govaluate.Parameters` interface. When you want to evaluate, instead call `EvaluableExpression.Eval` and pass your parameter structure.
-
-# Functions
-
-During expression parsing (_not_ evaluation), a map of functions can be given to `govaluate.NewEvaluableExpressionWithFunctions` (the lengthiest and finest of function names). The resultant expression will be able to invoke those functions during evaluation. Once parsed, an expression cannot have functions added or removed - a new expression will need to be created if you want to change the functions, or behavior of said functions.
-
-Functions always take the form `<name>(<parameters>)`, including parens. Functions can have an empty list of parameters, like `<name>()`, but still must have parens.
-
-If the expression contains something that looks like it ought to be a function (such as `foo()`), but no such function was given to it, it will error on parsing.
-
-Functions must be of type `map[string]govaluate.ExpressionFunction`. `ExpressionFunction`, for brevity, has the following signature:
-
-`func(args ...interface{}) (interface{}, error)`
-
-Where `args` is whatever is passed to the function when called. If a non-nil error is returned from a function during evaluation, the evaluation stops and ultimately returns that error to the caller of `Evaluate()` or `Eval()`.
-
-## Built-in functions
-
-There aren't any builtin functions. The author is opposed to maintaining a standard library of functions to be used.
-
-Every use case of this library is different, and even in simple use cases (such as parameters, see above) different users need different behavior, naming, or even functionality. The author prefers that users make their own decisions about what functions they need, and how they operate.
-
-# Equality
-
-The `==` and `!=` operators involve a moderately complex workflow. They use [`reflect.DeepEqual`](https://golang.org/pkg/reflect/#DeepEqual). This is for complicated reasons, but there are some types in Go that cannot be compared with the native `==` operator. Arrays, in particular, cannot be compared - Go will panic if you try. One might assume this could be handled with the type checking system in `govaluate`, but unfortunately without reflection there is no way to know if a variable is a slice/array. Worse, structs can be incomparable if they _contain incomparable types_.
-
-It's all very complicated. Fortunately, Go includes the `reflect.DeepEqual` function to handle all the edge cases. Currently, `govaluate` uses that for all equality/inequality.

-
-
-Provides support for evaluating arbitrary C-like artithmetic/string expressions.
-
-Why can't you just write these expressions in code?
---
-
-Sometimes, you can't know ahead-of-time what an expression will look like, or you want those expressions to be configurable.
-Perhaps you've got a set of data running through your application, and you want to allow your users to specify some validations to run on it before committing it to a database. Or maybe you've written a monitoring framework which is capable of gathering a bunch of metrics, then evaluating a few expressions to see if any metrics should be alerted upon, but the conditions for alerting are different for each monitor.
-
-A lot of people wind up writing their own half-baked style of evaluation language that fits their needs, but isn't complete. Or they wind up baking the expression into the actual executable, even if they know it's subject to change. These strategies may work, but they take time to implement, time for users to learn, and induce technical debt as requirements change. This library is meant to cover all the normal C-like expressions, so that you don't have to reinvent one of the oldest wheels on a computer.
-
-How do I use it?
---
-
-You create a new EvaluableExpression, then call "Evaluate" on it.
-
-```go
-	expression, err := govaluate.NewEvaluableExpression("10 > 0");
-	result, err := expression.Evaluate(nil);
-	// result is now set to "true", the bool value.
-```
-
-Cool, but how about with parameters?
-
-```go
-	expression, err := govaluate.NewEvaluableExpression("foo > 0");
-
-	parameters := make(map[string]interface{}, 8)
-	parameters["foo"] = -1;
-
-	result, err := expression.Evaluate(parameters);
-	// result is now set to "false", the bool value.
-```
-
-That's cool, but we can almost certainly have done all that in code. What about a complex use case that involves some math?
-
-```go
-	expression, err := govaluate.NewEvaluableExpression("(requests_made * requests_succeeded / 100) >= 90");
-
-	parameters := make(map[string]interface{}, 8)
-	parameters["requests_made"] = 100;
-	parameters["requests_succeeded"] = 80;
-
-	result, err := expression.Evaluate(parameters);
-	// result is now set to "false", the bool value.
-```
-
-Or maybe you want to check the status of an alive check ("smoketest") page, which will be a string?
-
-```go
-	expression, err := govaluate.NewEvaluableExpression("http_response_body == 'service is ok'");
-
-	parameters := make(map[string]interface{}, 8)
-	parameters["http_response_body"] = "service is ok";
-
-	result, err := expression.Evaluate(parameters);
-	// result is now set to "true", the bool value.
-```
-
-These examples have all returned boolean values, but it's equally possible to return numeric ones.
-
-```go
-	expression, err := govaluate.NewEvaluableExpression("(mem_used / total_mem) * 100");
-
-	parameters := make(map[string]interface{}, 8)
-	parameters["total_mem"] = 1024;
-	parameters["mem_used"] = 512;
-
-	result, err := expression.Evaluate(parameters);
-	// result is now set to "50.0", the float64 value.
-```
-
-You can also do date parsing, though the formats are somewhat limited. Stick to RF3339, ISO8061, unix date, or ruby date formats. If you're having trouble getting a date string to parse, check the list of formats actually used: [parsing.go:248](https://github.com/Knetic/govaluate/blob/0580e9b47a69125afa0e4ebd1cf93c49eb5a43ec/parsing.go#L258).
-
-```go
-	expression, err := govaluate.NewEvaluableExpression("'2014-01-02' > '2014-01-01 23:59:59'");
-	result, err := expression.Evaluate(nil);
-
-	// result is now set to true
-```
-
-Expressions are parsed once, and can be re-used multiple times. Parsing is the compute-intensive phase of the process, so if you intend to use the same expression with different parameters, just parse it once. Like so;
-
-```go
-	expression, err := govaluate.NewEvaluableExpression("response_time <= 100");
-	parameters := make(map[string]interface{}, 8)
-
-	for {
-		parameters["response_time"] = pingSomething();
-		result, err := expression.Evaluate(parameters)
-	}
-```
-
-The normal C-standard order of operators is respected. When writing an expression, be sure that you either order the operators correctly, or use parenthesis to clarify which portions of an expression should be run first.
-
-Escaping characters
---
-
-Sometimes you'll have parameters that have spaces, slashes, pluses, ampersands or some other character
-that this library interprets as something special. For example, the following expression will not
-act as one might expect:
-
-	"response-time < 100"
-
-As written, the library will parse it as "[response] minus [time] is less than 100". In reality,
-"response-time" is meant to be one variable that just happens to have a dash in it.
-
-There are two ways to work around this. First, you can escape the entire parameter name:
-
- 	"[response-time] < 100"
-
-Or you can use backslashes to escape only the minus sign.
-
-	"response\\-time < 100"
-
-Backslashes can be used anywhere in an expression to escape the very next character. Square bracketed parameter names can be used instead of plain parameter names at any time.
-
-Functions
---
-
-You may have cases where you want to call a function on a parameter during execution of the expression. Perhaps you want to aggregate some set of data, but don't know the exact aggregation you want to use until you're writing the expression itself. Or maybe you have a mathematical operation you want to perform, for which there is no operator; like `log` or `tan` or `sqrt`. For cases like this, you can provide a map of functions to `NewEvaluableExpressionWithFunctions`, which will then be able to use them during execution. For instance;
-
-```go
-	functions := map[string]govaluate.ExpressionFunction {
-		"strlen": func(args ...interface{}) (interface{}, error) {
-			length := len(args[0].(string))
-			return (float64)(length), nil
-		},
-	}
-
-	expString := "strlen('someReallyLongInputString') <= 16"
-	expression, _ := govaluate.NewEvaluableExpressionWithFunctions(expString, functions)
-
-	result, _ := expression.Evaluate(nil)
-	// result is now "false", the boolean value
-```
-
-Functions can accept any number of arguments, correctly handles nested functions, and arguments can be of any type (even if none of this library's operators support evaluation of that type). For instance, each of these usages of functions in an expression are valid (assuming that the appropriate functions and parameters are given):
-
-```go
-"sqrt(x1 ** y1, x2 ** y2)"
-"max(someValue, abs(anotherValue), 10 * lastValue)"
-```
-
-Functions cannot be passed as parameters, they must be known at the time when the expression is parsed, and are unchangeable after parsing.
-
-What operators and types does this support?
---
-
-* Modifiers: `+` `-` `/` `*` `&` `|` `^` `**` `%` `>>` `<<`
-* Comparators: `>` `>=` `<` `<=` `==` `!=` `=~` `!~`
-* Logical ops: `||` `&&`
-* Numeric constants, as 64-bit floating point (`12345.678`)
-* String constants (single quotes: `'foobar'`)
-* Date constants (single quotes, using any permutation of RFC3339, ISO8601, ruby date, or unix date; date parsing is automatically tried with any string constant)
-* Boolean constants: `true` `false`
-* Parenthesis to control order of evaluation `(` `)`
-* Arrays (anything separated by `,` within parenthesis: `(1, 2, 'foo')`)
-* Prefixes: `!` `-` `~`
-* Ternary conditional: `?` `:`
-* Null coalescence: `??`
-
-See [MANUAL.md](https://github.com/Knetic/govaluate/blob/master/MANUAL.md) for exacting details on what types each operator supports.
-
-Types
---
-
-Some operators don't make sense when used with some types. For instance, what does it mean to get the modulo of a string? What happens if you check to see if two numbers are logically AND'ed together?
-
-Everyone has a different intuition about the answers to these questions. To prevent confusion, this library will _refuse to operate_ upon types for which there is not an unambiguous meaning for the operation. See [MANUAL.md](https://github.com/Knetic/govaluate/blob/master/MANUAL.md) for details about what operators are valid for which types.
-
-Benchmarks
---
-
-If you're concerned about the overhead of this library, a good range of benchmarks are built into this repo. You can run them with `go test -bench=.`. The library is built with an eye towards being quick, but has not been aggressively profiled and optimized. For most applications, though, it is completely fine.
-
-For a very rough idea of performance, here are the results output from a benchmark run on a 3rd-gen Macbook Pro (Linux Mint 17.1).

-API Breaks
---
-
-While this library has very few cases which will ever result in an API break, it can (and [has](https://github.com/Knetic/govaluate/releases/tag/2.0.0)) happened. If you are using this in production, vendor the commit you've tested against, or use gopkg.in to redirect your import (e.g., `import "gopkg.in/Knetic/govaluate.v2"`). Master branch (while infrequent) _may_ at some point contain API breaking changes, and the author will have no way to communicate these to downstreams, other than creating a new major release.
-
-Releases will explicitly state when an API break happens, and if they do not specify an API break it should be safe to upgrade.
-
-License

-
-This project is licensed under the MIT general use license. You're free to integrate, fork, and play with this code as you feel fit without consulting the author, as long as you provide proper credit to the author in your works.

-x2j.go - Unmarshal dynamic / arbitrary XML docs and extract values (using wildcards, if necessary).
-
-ANNOUNCEMENTS
-
-20 December 2013:
-
-Non-UTF8 character sets supported via the X2jCharsetReader variable.
-
-12 December 2013:
-
-For symmetry, the package j2x has functions that marshal JSON strings and
-map[string]interface{} values to XML encoded strings: http://godoc.org/github.com/clbanning/j2x.
-
-Also, ToTree(), ToMap(), ToJson(), ToJsonIndent(), ReaderValuesFromTagPath() and ReaderValuesForTag() use io.Reader instead of string or []byte.
-
-If you want to process a stream of XML messages check out XmlMsgsFromReader().
-
-MOTIVATION
-
-I make extensive use of JSON for messaging and typically unmarshal the messages into
-map[string]interface{} variables.  This is easily done using json.Unmarshal from the
-standard Go libraries.  Unfortunately, many legacy solutions use structured
-XML messages; in those environments the applications would have to be refitted to
-interoperate with my components.
-
-The better solution is to just provide an alternative HTTP handler that receives
-XML doc messages and parses it into a map[string]interface{} variable and then reuse
-all the JSON-based code.  The Go xml.Unmarshal() function does not provide the same
-option of unmarshaling XML messages into map[string]interface{} variables. So I wrote
-a couple of small functions to fill this gap.
-
-Of course, once the XML doc was unmarshal'd into a map[string]interface{} variable it
-was just a matter of calling json.Marshal() to provide it as a JSON string.  Hence 'x2j'
-rather than just 'x2m'.
-
-USAGE
-
-The package is fairly well self-documented. (http://godoc.org/github.com/clbanning/x2j)  
-The one really useful function is:
-
-    - Unmarshal(doc []byte, v interface{}) error  
-      where v is a pointer to a variable of type 'map[string]interface{}', 'string', or
-      any other type supported by xml.Unmarshal().
-
-To retrieve a value for specific tag use: 
-
-    - DocValue(doc, path string, attrs ...string) (interface{},error) 
-    - MapValue(m map[string]interface{}, path string, attr map[string]interface{}, recast ...bool) (interface{}, error)
-
-The 'path' argument is a period-separated tag hierarchy - also known as dot-notation.
-It is the program's responsibility to cast the returned value to the proper type; possible 
-types are the normal JSON unmarshaling types: string, float64, bool, []interface, map[string]interface{}.  
-
-To retrieve all values associated with a tag occurring anywhere in the XML document use:
-
-    - ValuesForTag(doc, tag string) ([]interface{}, error)
-    - ValuesForKey(m map[string]interface{}, key string) []interface{}
-
-    Demos: http://play.golang.org/p/m8zP-cpk0O
-           http://play.golang.org/p/cIteTS1iSg
-           http://play.golang.org/p/vd8pMiI21b
-
-Returned values should be one of map[string]interface, []interface{}, or string.
-
-All the values assocated with a tag-path that may include one or more wildcard characters - 
-'*' - can also be retrieved using:
-
-    - ValuesFromTagPath(doc, path string, getAttrs ...bool) ([]interface{}, error)
-    - ValuesFromKeyPath(map[string]interface{}, path string, getAttrs ...bool) []interface{}
-
-    Demos: http://play.golang.org/p/kUQnZ8VuhS
-           http://play.golang.org/p/l1aMHYtz7G
-
-NOTE: care should be taken when using "*" at the end of a path - i.e., "books.book.*".  See
-the x2jpath_test.go case on how the wildcard returns all key values and collapses list values;
-the same message structure can load a []interface{} or a map[string]interface{} (or an interface{}) 
-value for a tag.
-
-See the test cases in "x2jpath_test.go" and programs in "example" subdirectory for more.
-
-XML PARSING CONVENTIONS
-
-   - Attributes are parsed to map[string]interface{} values by prefixing a hyphen, '-',
-     to the attribute label.
-   - If the element is a simple element and has attributes, the element value
-     is given the key '#text' for its map[string]interface{} representation.  (See
-     the 'atomFeedString.xml' test data, below.)
-
-BULK PROCESSING OF MESSAGE FILES
-
-Sometime messages may be logged into files for transmission via FTP (e.g.) and subsequent
-processing. You can use the bulk XML message processor to convert files of XML messages into 
-map[string]interface{} values with custom processing and error handler functions.  See
-the notes and test code for:
-
-   - XmlMsgsFromFile(fname string, phandler func(map[string]interface{}) bool, ehandler func(error) bool,recast ...bool) error
-
-IMPLEMENTATION NOTES
-
-Nothing fancy here, just brute force.
-
-   - Use xml.Decoder to parse the XML doc and build a tree.
-   - Walk the tree and load values into a map[string]interface{} variable, 'm', as
-     appropriate.
-   - Use json.Marshaler to convert 'm' to JSON.
-
-As for testing:
-
-   - Copy an XML doc into 'x2j_test.xml'.
-   - Run "go test" and you'll get a full dump.
-     ("pathTestString.xml" and "atomFeedString.xml" are test data from "read_test.go"
-     in the encoding/xml directory of the standard package library.)
-
-USES
-
-   - putting a XML API on our message hub middleware (http://jsonhub.net)
-   - loading XML data into NoSQL database, such as, mongoDB
-
-PERFORMANCE IMPROVEMENTS WITH GO 1.1 and 1.2
-
-Upgrading to Go 1.1 environment results in performance improvements for XML and JSON
-unmarshalling, in general.  The x2j package gets an average performance boost of 40%.

-  An attempt at adding pubsubhubbub support to Rietveld.
-http://code.google.com/p/pubsubhubbub
-http://code.google.com/p/rietveld/issues/detail?id=155
-
-The server side of the protocol is trivial:
-  1. add a &amp;lt;link rel=&amp;quot;hub&amp;quot; href=&amp;quot;hub-server&amp;quot;&amp;gt; tag to all
-     feeds that will be pubsubhubbubbed.
-  2. every time one of those feeds changes, tell the hub
-     with a simple POST request.
-
-I have tested this by adding debug prints to a local hub
-server and checking that the server got the right publish
-requests.
-
-I can&amp;#39;t quite get the server to work, but I think the bug
-is not in my code.  I think that the server expects to be
-able to grab the feed and see the feed&amp;#39;s actual URL in
-the link rel=&amp;quot;self&amp;quot;, but the default value for that drops
-the :port from the URL, and I cannot for the life of me
-figure out how to get the Atom generator deep inside
-django not to do that, or even where it is doing that,
-or even what code is running to generate the Atom feed.
-(I thought I knew but I added some assert False statements
-and it kept running!)
-
-Ignoring that particular problem, I would appreciate
-feedback on the right way to get the two values at
-the top of feeds.py marked NOTE(rsc).

-  This fixes the buggy tab rendering that can be seen at
-http://codereview.appspot.com/116075/diff/1/2
-
-The fundamental problem was that the tab code was
-not being told what column the text began in, so it
-didn&amp;#39;t know where to put the tab stops.  Another problem
-was that some of the code assumed that string byte
-offsets were the same as column offsets, which is only
-true if there are no tabs.
-
-In the process of fixing this, I cleaned up the arguments
-to Fold and ExpandTabs and renamed them Break and
-_ExpandTabs so that I could be sure that I found all the
-call sites.  I also wanted to verify that ExpandTabs was
-not being used from outside intra_region_diff.py.

-   Unmarshal dynamic / arbitrary XML docs and extract values (using wildcards, if necessary).
-
-   One useful function is:
-
-       - Unmarshal(doc []byte, v interface{}) error  
-         where v is a pointer to a variable of type 'map[string]interface{}', 'string', or
-         any other type supported by xml.Unmarshal().
-
-   To retrieve a value for specific tag use: 
-
-       - DocValue(doc, path string, attrs ...string) (interface{},error) 
-       - MapValue(m map[string]interface{}, path string, attr map[string]interface{}, recast ...bool) (interface{}, error)
-
-   The 'path' argument is a period-separated tag hierarchy - also known as dot-notation.
-   It is the program's responsibility to cast the returned value to the proper type; possible 
-   types are the normal JSON unmarshaling types: string, float64, bool, []interface, map[string]interface{}.  
-
-   To retrieve all values associated with a tag occurring anywhere in the XML document use:
-
-       - ValuesForTag(doc, tag string) ([]interface{}, error)
-       - ValuesForKey(m map[string]interface{}, key string) []interface{}
-
-       Demos: http://play.golang.org/p/m8zP-cpk0O
-              http://play.golang.org/p/cIteTS1iSg
-              http://play.golang.org/p/vd8pMiI21b
-
-   Returned values should be one of map[string]interface, []interface{}, or string.
-
-   All the values assocated with a tag-path that may include one or more wildcard characters - 
-   '*' - can also be retrieved using:
-
-       - ValuesFromTagPath(doc, path string, getAttrs ...bool) ([]interface{}, error)
-       - ValuesFromKeyPath(map[string]interface{}, path string, getAttrs ...bool) []interface{}
-
-       Demos: http://play.golang.org/p/kUQnZ8VuhS
-   	        http://play.golang.org/p/l1aMHYtz7G
-
-   NOTE: care should be taken when using "*" at the end of a path - i.e., "books.book.*".  See
-   the x2jpath_test.go case on how the wildcard returns all key values and collapses list values;
-   the same message structure can load a []interface{} or a map[string]interface{} (or an interface{}) 
-   value for a tag.
-
-   See the test cases in "x2jpath_test.go" and programs in "example" subdirectory for more.
-
-   XML PARSING CONVENTIONS
-
-      - Attributes are parsed to map[string]interface{} values by prefixing a hyphen, '-',
-        to the attribute label.
-      - If the element is a simple element and has attributes, the element value
-        is given the key '#text' for its map[string]interface{} representation.  (See
-        the 'atomFeedString.xml' test data, below.)
-
-    io.Reader HANDLING
-
-    ToTree(), ToMap(), ToJson(), and ToJsonIndent() provide parsing of messages from an io.Reader.
-    If you want to handle a message stream, look at XmlMsgsFromReader().
-
-    NON-UTF8 CHARACTER SETS
-
-    Use the X2jCharsetReader variable to assign io.Reader for alternative character sets.

-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its

-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.

-
-Casbin is a powerful and efficient open-source access control library for Golang projects. It provides support for enforcing authorization based on various [access control models](https://en.wikipedia.org/wiki/Computer_security_model).
-
-## All the languages supported by Casbin:
-
-- Golang: [Casbin](https://github.com/casbin/casbin) (production-ready)
-- Java: [jCasbin](https://github.com/casbin/jcasbin) (production-ready)
-- PHP: [PHP-Casbin](https://github.com/sstutz/php-casbin) (experimental)
-- Node.js: [node-casbin](https://github.com/casbin/node-casbin) (WIP)
-- C++: xCasbin (WIP)

-## Supported models
-
-1. [**ACL (Access Control List)**](https://en.wikipedia.org/wiki/Access_control_list)
-2. **ACL with [superuser](https://en.wikipedia.org/wiki/Superuser)**
-3. **ACL without users**: especially useful for systems that don't have authentication or user log-ins.
-3. **ACL without resources**: some scenarios may target for a type of resources instead of an individual resource by using permissions like ``write-article``, ``read-log``. It doesn't control the access to a specific article or log.
-4. **[RBAC (Role-Based Access Control)](https://en.wikipedia.org/wiki/Role-based_access_control)**
-5. **RBAC with resource roles**: both users and resources can have roles (or groups) at the same time.
-6. **RBAC with domains/tenants**: users can have different role sets for different domains/tenants.
-7. **[ABAC (Attribute-Based Access Control)](https://en.wikipedia.org/wiki/Attribute-Based_Access_Control)**: syntax sugar like ``resource.Owner`` can be used to get the attribute for a resource.
-8. **[RESTful](https://en.wikipedia.org/wiki/Representational_state_transfer)**: supports paths like ``/res/*``, ``/res/:id`` and HTTP methods like ``GET``, ``POST``, ``PUT``, ``DELETE``.
-9. **Deny-override**: both allow and deny authorizations are supported, deny overrides the allow.
-10. **Priority**: the policy rules can be prioritized like firewall rules.
-
-## How it works?
-
-In Casbin, an access control model is abstracted into a CONF file based on the **PERM metamodel (Policy, Effect, Request, Matchers)**. So switching or upgrading the authorization mechanism for a project is just as simple as modifying a configuration. You can customize your own access control model by combining the available models. For example, you can get RBAC roles and ABAC attributes together inside one model and share one set of policy rules.
-
-The most basic and simplest model in Casbin is ACL. ACL's model CONF is:
-
-```ini
-# Request definition
-[request_definition]
-r = sub, obj, act
-
-# Policy definition
-[policy_definition]
-p = sub, obj, act
-
-# Policy effect
-[policy_effect]
-e = some(where (p.eft == allow))
-
-# Matchers
-[matchers]
-m = r.sub == p.sub && r.obj == p.obj && r.act == p.act
-
-# We also support multi-line mode by appending '\' in the end:
-# m = r.sub == p.sub && r.obj == p.obj \ 
-#  && r.act == p.act
-```
-
-An example policy for ACL model is like:
-
-```
-p, alice, data1, read
-p, bob, data2, write
-```
-
-It means:
-
-- alice can read data1
-- bob can write data2
-
-## Features
-
-What Casbin does:
-
-1. enforce the policy in the classic ``{subject, object, action}`` form or a customized form as you defined, both allow and deny authorizations are supported.
-2. handle the storage of the access control model and its policy.
-3. manage the role-user mappings and role-role mappings (aka role hierarchy in RBAC).
-4. support built-in superuser like ``root`` or ``administrator``. A superuser can do anything without explict permissions.
-5. multiple built-in operators to support the rule matching. For example, ``keyMatch`` can map a resource key ``/foo/bar`` to the pattern ``/foo*``.
-
-What Casbin does NOT do:
-
-1. authentication (aka verify ``username`` and ``password`` when a user logs in)
-2. manage the list of users or roles. I believe it's more convenient for the project itself to manage these entities. Users usually have their passwords, and Casbin is not designed as a password container. However, Casbin stores the user-role mapping for the RBAC scenario. 
-
-## Installation
-
-```
-go get github.com/casbin/casbin
-```
-
-## Documentation
-
-For documentation, please see: [Our Wiki](https://github.com/casbin/casbin/wiki)
-
-## Online editor
-
-You can also use the online editor (http://casbin.org/editor/) to write your Casbin model and policy in your web browser. It provides functionality such as ``syntax highlighting`` and ``code completion``, just like an IDE for a programming language.

-- [Using Casbin with Beego: 4. Policy update (in Chinese)](https://blog.csdn.net/hotqin888/article/details/80032538)
-
-## Get started
-
-1. New a Casbin enforcer with a model file and a policy file:
-
-    ```go
-    e := casbin.NewEnforcer("path/to/model.conf", "path/to/policy.csv")
-    ```
-
-Note: you can also initialize an enforcer with policy in DB instead of file, see [Persistence](#persistence) section for details.
-
-2. Add an enforcement hook into your code right before the access happens:
-
-    ```go
-    sub := "alice" // the user that wants to access a resource.
-    obj := "data1" // the resource that is going to be accessed.
-    act := "read" // the operation that the user performs on the resource.
-
-    if e.Enforce(sub, obj, act) == true {
-        // permit alice to read data1
-    } else {
-        // deny the request, show an error
-    }
-    ```
-
-3. Besides the static policy file, Casbin also provides API for permission management at run-time. For example, You can get all the roles assigned to a user as below:
-
-    ```go
-    roles := e.GetRoles("alice")
-    ```
-
-See [Policy management APIs](#policy-management) for more usage.
-
-4. Please refer to the ``_test.go`` files for more usage.
-
-## Policy management
-
-Casbin provides two sets of APIs to manage permissions:
-
-- [Management API](https://github.com/casbin/casbin/blob/master/management_api.go): the primitive API that provides full support for Casbin policy management. See [here](https://github.com/casbin/casbin/blob/master/management_api_test.go) for examples.
-- [RBAC API](https://github.com/casbin/casbin/blob/master/rbac_api.go): a more friendly API for RBAC. This API is a subset of Management API. The RBAC users could use this API to simplify the code. See [here](https://github.com/casbin/casbin/blob/master/rbac_api_test.go) for examples.
-
-We also provide a web-based UI for model management and policy management:
-
-![model editor](https://hsluoyz.github.io/casbin/ui_model_editor.png)
-
-![policy editor](https://hsluoyz.github.io/casbin/ui_policy_editor.png)
-
-## Policy persistence
-
-In Casbin, the policy storage is implemented as an adapter (aka middleware for Casbin). To keep light-weight, we don't put adapter code in the main library (except the default file adapter). A complete list of Casbin adapters is provided as below. Any 3rd-party contribution on a new adapter is welcomed, please inform us and I will put it in this list:)

-
-## Policy enforcement at scale
-
-Some adapters support filtered policy management. This means that the policy loaded by Casbin is a subset of the policy in storage based on a given filter. This allows for efficient policy enforcement in large, multi-tenant environments when parsing the entire policy becomes a performance bottleneck.
-
-To use filtered policies with a supported adapter, simply call the `LoadFilteredPolicy` method. The valid format for the filter parameter depends on the adapter used. To prevent accidental data loss, the `SavePolicy` method is disabled when a filtered policy is loaded.
-
-For example, the following code snippet uses the built-in filtered file adapter and the RBAC model with domains. In this case, the filter limits the policy to a single domain. Any policy lines for domains other than `"domain1"` are omitted from the loaded policy:
-
-```go
-import (
-    "github.com/casbin/casbin"
-)
-
-enforcer := casbin.NewEnforcer()
-
-adapter := fileadapter.NewFilteredAdapter("examples/rbac_with_domains_policy.csv")
-enforcer.InitWithAdapter("examples/rbac_with_domains_model.conf", adapter)
-
-filter := &fileadapter.Filter{
-    P: []string{"", "domain1"},
-    G: []string{"", "", "domain1"},
-}
-enforcer.LoadFilteredPolicy(filter)
-
-// The loaded policy now only contains the entries pertaining to "domain1".
-```
-
-## Policy consistence between multiple nodes
-
-We support to use distributed messaging systems like [etcd](https://github.com/coreos/etcd) to keep consistence between multiple Casbin enforcer instances. So our users can concurrently use multiple Casbin enforcers to handle large number of permission checking requests.
-
-Similar to policy storage adapters, we don't put watcher code in the main library. Any support for a new messaging system should be implemented as a watcher. A complete list of Casbin watchers is provided as below. Any 3rd-party contribution on a new watcher is welcomed, please inform us and I will put it in this list:)

-## Role manager
-
-The role manager is used to manage the RBAC role hierarchy (user-role mapping) in Casbin. A role manager can retrieve the role data from Casbin policy rules or external sources such as LDAP, Okta, Auth0, Azure AD, etc. We support different implementations of a role manager. To keep light-weight, we don't put role manager code in the main library (except the default role manager). A complete list of Casbin role managers is provided as below. Any 3rd-party contribution on a new role manager is welcomed, please inform us and I will put it in this list:)
-
-Role manager | Author | Description
-----|----|----
-[Default Role Manager (built-in)](https://github.com/casbin/casbin/blob/master/rbac/default-role-manager/role_manager.go) | Casbin | Supports role hierarchy stored in Casbin policy
-[Session Role Manager](https://github.com/casbin/session-role-manager) | [EDOMO Systems](https://github.com/edomosystems) | Supports role hierarchy stored in Casbin policy, with time-range-based sessions
-[Okta Role Manager](https://github.com/casbin/okta-role-manager) | Casbin | Supports role hierarchy stored in [Okta](https://www.okta.com/)
-[Auth0 Role Manager](https://github.com/casbin/auth0-role-manager) | Casbin | Supports role hierarchy stored in [Auth0](https://auth0.com/)'s [Authorization Extension](https://auth0.com/docs/extensions/authorization-extension/v2)
-
-For developers: all role managers must implement the [RoleManager](https://github.com/casbin/casbin/blob/master/rbac/role_manager.go) interface. [Session Role Manager](https://github.com/casbin/session-role-manager) can be used as a reference implementation.
-
-## Multi-threading
-
-If you use Casbin in a multi-threading manner, you can use the synchronized wrapper of the Casbin enforcer: https://github.com/casbin/casbin/blob/master/enforcer_synced.go.
-
-It also supports the ``AutoLoad`` feature, which means the Casbin enforcer will automatically load the latest policy rules from DB if it has changed. Call ``StartAutoLoadPolicy()`` to start automatically loading policy periodically and call ``StopAutoLoadPolicy()`` to stop it.
-
-## Benchmarks
-
-The overhead of policy enforcement is benchmarked in [model_b_test.go](https://github.com/casbin/casbin/blob/master/model_b_test.go). The testbed is:
-
-```
-Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz, 2601 Mhz, 4 Core(s), 8 Logical Processor(s)
-```
-
-The benchmarking result of ``go test -bench=. -benchmem`` is as follows (op = an ``Enforce()`` call, ms = millisecond, KB = kilo bytes):
-
-Test case | Size | Time overhead | Memory overhead
-----|------|------|----
