## What is XML-Comp
This is a command line tool and a package that together they provide the capability of comparing two directories and appending to files the differences between the directories, also creates possible files or folders that are missing. It was made to help [RimWorld](http://rimworldgame.com/)'s [community translators](https://github.com/ludeon)(1) to know what was modified on the last XML updates and to let them keep in track of what they need to add/remove from what has been done.

(1) and maybe other indie games that uses XML

### Features
- [x] [Compare two given directories](https://github.com/XML-Comp/XML-Comp/issues/7)
- [x] [Append missing tags to the respective file](https://github.com/XML-Comp/XML-Comp/issues/8)
- [x] [Creates missing files on the compared directory](https://github.com/XML-Comp/XML-Comp/issues/9)
- [x] [Creates missing folders on the compared directory](https://github.com/XML-Comp/XML-Comp/issues/32)
- [x] [Compare one directory with multiple directories](https://github.com/XML-Comp/XML-Comp/issues/48)
- [x] [Compare automatically the game's english version with the given translation](https://github.com/XML-Comp/XML-Comp/issues?q=is%3Aissue+is%3Aclosed)
- [ ] Translate tag content
- [ ] Expose untracked files
- [ ] Expose untracked directories
- [ ] Expose untracked tags

### Installing
```
$ go get github.com/XML-Comp/XML-Comp
```

### Running
```shell
$ XML-Comp -translation /path/to/language/translation
```

### How this works?
You need the path that is called "translation", which are described bellow:
- **`"translation"`**: Full path directory of your RimWorld ~Language~ folder cloned from [GitHub](https://github.com/ludeon).

My "translation" path: **`/Users/arthur/Github/RimWorld-PortugueseBrazilian`**

With this path in hand, running `xml-comp -translation your/path/to/translation` will let you know in every file of your project what is missing by adding lines to it with what is needed to translate! That simple!

#### [RIMWORLD not installed in standard path]
If by any reason you did not install the game on Steam's standard path or want to use a different one, It's possible to use the `original` flag that exposes your customized path to the game as shows: 

- **`"original"`**: Full path directory of your RimWorld English folder (optional).
My "original" path (optional): **`/Users/arthur/Library/Application Support/Steam/steamapps/common/RimWorld/RimWorldMac.app/Mods/Core/Languages/English`**

In order to use this flag you'll need to parse it with the `translation` flag as in: `xml-comp -original path/... -translation path/...`

#### Comparing any kind of document
To compare any kind of files, all you need is to use the flag `-doc <type name>`, eg `-doc html`. This will use the paths that you gave only to compare the specified type of document. Another example:

```shell
$ XML-Comp -doc html -original path/to/It -translation path/to/It
```

OBS: This is not required, by default It's comparing all `.xml` files that are encountered.

## Using only the comparer package
```go
// Import the package
import "github.com/XML-Comp/XML-Comp/comparer"
// Set document type variable to the desired document
// without the "." | eg: "xml" or "html"
comparer.DocType = "html"
// Start the main function with the full paths to compare
// the firstPath is always what will be used as model
func main() {
    err := comparer.Compare(firstPath, comparingPath)
    if err != nil {
        log.Fatal(err)
    }
}
```

# xml2map
XML to MAP converter written Golang

Sometimes there is a need for the representation of previously unknown structures. Such a universal representation is usually a string in the form of JSON, XML, or the structure of data map. similar to the map[string]interface{} or map[interface{}]interface{}.

This is a converter from the old XML format to map[string]interface{} Golang

For example, the map[string]interface{} can be used as a universal type in template generation. Golang "text/template" and etc.

## Getting started

#### 1. install 

``` sh
go get -u github.com/sbabiv/xml2map
```

Or, using dep:

``` sh
dep ensure -add github.com/sbabiv/xml2map
```


#### 2. use it

```go

func main() {
	data := `<container uid="FA6666D9-EC9F-4DA3-9C3D-4B2460A4E1F6" lifetime="2019-10-10T18:00:11">
				<cats>
					<cat>
						<id>CDA035B6-D453-4A17-B090-84295AE2DEC5</id>
						<name>moritz</name>
						<age>7</age> 	
						<items>
							<n>1293</n>
							<n>1255</n>
							<n>1257</n>
						</items>
					</cat>
					<cat>
						<id>1634C644-975F-4302-8336-1EF1366EC6A4</id>
						<name>oliver</name>
						<age>12</age>
					</cat>
					<dog color="gray">hello</dog>
				</cats>
				<color>white</color>
				<city>NY</city>
			</container>`

	decoder := xml2map.NewDecoder(strings.NewReader(data))
	result, err := decoder.Decode()

	if err != nil {
		fmt.Printf("%v\n", err)
	} else {
		fmt.Printf("%v\n", result)
	}
	
	v := result["container"].
		(map[string]interface{})["cats"].
			(map[string]interface{})["cat"].
				([]map[string]interface{})[0]["items"].
					(map[string]interface{})["n"].([]string)[1]
					
	fmt.Printf("n[1]: %v\n", v)
}

```
if you want to use your custom prefixes use the 

```
NewDecoderWithPrefix(reader io.Reader, attrPrefix, textPrefix string) *Decoder
```
[Go Playground](https://play.golang.org/p/_n35DRTxTYF)

## Output

```go
map[container:map[@uid:FA6666D9-EC9F-4DA3-9C3D-4B2460A4E1F6 @lifetime:2019-10-10T18:00:11 cats:map[cat:[map[id:CDA035B6-D453-4A17-B090-84295AE2DEC5 name:moritz age:7 items:map[n:[1293 1255 1257]]] map[id:1634C644-975F-4302-8336-1EF1366EC6A4 name:oliver age:12]] dog:map[@color:gray #text:hello]] color:white city:NY]]

xml2map

Procedural XML generation API based on libxml2's xmlwriter module.

xmlwriter
=========

[![GoDoc](https://godoc.org/github.com/shabbyrobe/xmlwriter?status.svg)](https://godoc.org/github.com/shabbyrobe/xmlwriter)
![Go](https://github.com/shabbyrobe/xmlwriter/workflows/Go/badge.svg)

xmlwriter is a pure-Go library providing a procedural XML generation API based
on libxml2's xmlwriter module. The package is extensively documented at
[GoDoc](https://godoc.org/github.com/shabbyrobe/xmlwriter).

Quick example:

```go
func main() {
    b := &bytes.Buffer{}
    w := xmlwriter.Open(b)
    ec := &xmlwriter.ErrCollector{}
    defer ec.Panic()

    ec.Do(
        w.StartDoc(xmlwriter.Doc{})
        w.StartElem(xmlwriter.Elem{Name: "foo"})
        w.WriteAttr(xmlwriter.Attr{Name: "a1", Value: "val1"})
        w.WriteAttr(xmlwriter.Attr{Name: "a2", Value: "val2"})
        w.WriteComment(xmlwriter.Comment{"hello"})
        w.StartElem(xmlwriter.Elem{Name: "bar"})
        w.WriteAttr(xmlwriter.Attr{Name: "a1", Value: "val1"})
        w.WriteAttr(xmlwriter.Attr{Name: "a2", Value: "val2"})
        w.StartElem(xmlwriter.Elem{Name: "baz"})
        w.EndAllFlush()
    )
    fmt.Println(b.String())
}
```

xmlwriter is about twice as quick as using the stdlib's `encoding/xml` and
offers total control of the output. If you don't require that level of control,
it's probably better to stick with `encoding/xml`

xmlwriter is exhaustively tested using a fairly insane mess of C scripts you
can find in the `tester/` directory.

# XPath

[![GoDoc](https://godoc.org/github.com/antchfx/xpath?status.svg)](https://godoc.org/github.com/antchfx/xpath)
[![Coverage Status](https://coveralls.io/repos/github/antchfx/xpath/badge.svg?branch=master)](https://coveralls.io/github/antchfx/xpath?branch=master)
[![Build Status](https://github.com/antchfx/xpath/actions/workflows/testing.yml/badge.svg)](https://github.com/antchfx/xpath/actions/workflows/testing.yml)
[![Go Report Card](https://goreportcard.com/badge/github.com/antchfx/xpath)](https://goreportcard.com/report/github.com/antchfx/xpath)

XPath is Go package provides selecting nodes from XML, HTML or other documents using XPath expression.

# Implementation

- [htmlquery](https://github.com/antchfx/htmlquery) - an XPath query package for HTML document

- [xmlquery](https://github.com/antchfx/xmlquery) - an XPath query package for XML document.

- [jsonquery](https://github.com/antchfx/jsonquery) - an XPath query package for JSON document

# Supported Features

#### The basic XPath patterns.

> The basic XPath patterns cover 90% of the cases that most stylesheets will need.

- `node` : Selects all child elements with nodeName of node.

- `*` : Selects all child elements.

- `@attr` : Selects the attribute attr.

- `@*` : Selects all attributes.

- `node()` : Matches an org.w3c.dom.Node.

- `text()` : Matches a org.w3c.dom.Text node.

- `comment()` : Matches a comment.

- `.` : Selects the current node.

- `..` : Selects the parent of current node.

- `/` : Selects the document node.

- `a[expr]` : Select only those nodes matching a which also satisfy the expression expr.

- `a[n]` : Selects the nth matching node matching a When a filter's expression is a number, XPath selects based on position.

- `a/b` : For each node matching a, add the nodes matching b to the result.

- `a//b` : For each node matching a, add the descendant nodes matching b to the result.

- `//b` : Returns elements in the entire document matching b.

- `a|b` : All nodes matching a or b, union operation(not boolean or).

- `(a, b, c)` : Evaluates each of its operands and concatenates the resulting sequences, in order, into a single result sequence

- `(a/b)` : Selects all matches nodes as grouping set.

#### Node Axes

- `child::*` : The child axis selects children of the current node.

  - `child::node()`: Selects all the children of the context node.
  - `child::text()`: Selects all text node children of the context node.

- `descendant::*` : The descendant axis selects descendants of the current node. It is equivalent to '//'.

- `descendant-or-self::*` : Selects descendants including the current node.

- `attribute::*` : Selects attributes of the current element. It is equivalent to @\*

- `following-sibling::*` : Selects nodes after the current node.

- `preceding-sibling::*` : Selects nodes before the current node.

- `following::*` : Selects the first matching node following in document order, excluding descendants.

- `preceding::*` : Selects the first matching node preceding in document order, excluding ancestors.

- `parent::*` : Selects the parent if it matches. The '..' pattern from the core is equivalent to 'parent::node()'.

- `ancestor::*` : Selects matching ancestors.

- `ancestor-or-self::*` : Selects ancestors including the current node.

- `self::*` : Selects the current node. '.' is equivalent to 'self::node()'.

#### Expressions

The gxpath supported three types: number, boolean, string.

- `path` : Selects nodes based on the path.

- `a = b` : Standard comparisons.

  - `a = b` : True if a equals b.
  - `a != b` : True if a is not equal to b.
  - `a < b` : True if a is less than b.
  - `a <= b` : True if a is less than or equal to b.
  - `a > b` : True if a is greater than b.
  - `a >= b` : True if a is greater than or equal to b.

- `a + b` : Arithmetic expressions.

  - `- a` Unary minus
  - `a + b` : Addition
  - `a - b` : Subtraction
  - `a * b` : Multiplication
  - `a div b` : Division
  - `a mod b` : Modulus (division remainder)

- `a or b` : Boolean `or` operation.

- `a and b` : Boolean `and` operation.

- `(expr)` : Parenthesized expressions.

- `fun(arg1, ..., argn)` : Function calls:
