xmldom is a javascript [ponyfill](https://ponyfill.com/) for the following APIs supported in browsers:
- convert an XML string into a DOM tree (`new DOMParser().parseFromString(xml, mimeType)` => `Document`)
- create, access and modify a DOM tree (`new DOMImplementation().createDocument(...)` => `Document`, )
- serialize a DOM tree back into an XML string (`new XMLSerializer().serializeToString(node)` => `string`)
Note that this `xmldom` library is not required if your code targets a modern browser. But this library is recommended if your code needs to also work in other runtimes like NodeJS or Rhino.
## Specs
The implementation is based on several specifications:
### DOM Parsing and Serialization
From the [W3C DOM Parsing and Serialization (WD 2016)](https://www.w3.org/TR/2016/WD-DOM-Parsing-20160517/) `xmldom` provides an implementation for the interfaces:
- `DOMParser`
- `XMLSerializer`
Note that there are some known deviations between this implementation and the W3 specifications.
Note: [The latest version of this spec](https://w3c.github.io/DOM-Parsing/) has the status "Editors Draft", since it is under active development. One major change is that [the definition of the `DOMParser` interface has been moved to the HTML spec](https://w3c.github.io/DOM-Parsing/#the-domparser-interface)
### DOM
The original author claims that xmldom implements [DOM Level 2] in a "fully compatible" way and some parts of [DOM Level 3], but there are not enough tests to prove this. Both Specifications are now superseded by the [DOM Level 4 aka Living standard] wich has a much broader scope than xmldom.
xmldom implements the following interfaces (most constructors are currently not exposed):
- `Attr`
- `CDATASection`
- `CharacterData`
- `Comment`
- `Document`
- `DocumentFragment`
- `DocumentType`
- `DOMException` (constructor exposed)
- `DOMImplementation` (constructor exposed)
- `Element`
- `Entity`
- `EntityReference`
- `LiveNodeList`
- `NamedNodeMap`
- `Node` (constructor exposed)
- `NodeList`
- `Notation`
- `ProcessingInstruction`
- `Text`
more details are available in the (incomplete) [API Reference](#api-reference) section.
### HTML
xmldom does not have any goal of supporting the full spec, but it has some capability to parse, report and serialize things differently when "detecting HTML" (by checking the default namespace).
There is an upcoming change to better align the implementation with the latest specs, related to .
### SAX, XML, XMLNS
xmldom has an own SAX parser implementation to do the actual parsing, which implements some interfaces in alignment with the Java interfaces SAX defines:
- `XMLReader`
- `DOMHandler`
There is an idea/proposal to make ti possible to replace it with something else in
## Forked

## Usage
### Install:
> npm install xmldom
### Example:
```javascript
const { DOMParser } = require('xmldom')
const doc = new DOMParser().parseFromString(
'\n' +
'\ttest\n' +
'\t\n' +
'\t\n' +
'',
'text/xml'
)
doc.documentElement.setAttribute('x', 'y')
doc.documentElement.setAttributeNS('./lite', 'c:x', 'y2')
console.info(doc)
const nsAttr = doc.documentElement.getAttributeNS('./lite', 'x')
console.info(nsAttr)
```
Note: in Typescript and ES6 you can use the import approach, as follows:
```javascript
import { DOMParser } from 'xmldom'
```
## API Reference
* [DOMParser](https://developer.mozilla.org/en-US/docs/Web/API/DOMParser):
```javascript
parseFromString(xmlsource,mimeType)
```
* **options extension** _by xmldom_(not BOM standard!!)
```javascript
//added the options argument
new DOMParser(options)
//errorHandler is supported
new DOMParser({
/**
* locator is always need for error position info
*/
locator:{},
/**
* you can override the errorHandler for xml parser
* @link http://www.saxproject.org/apidoc/org/xml/sax/ErrorHandler.html
*/
errorHandler:{warning:function(w){console.warn(w)},error:callback,fatalError:callback}
//only callback model
//errorHandler:function(level,msg){console.log(level,msg)}
})
```
* [XMLSerializer](https://developer.mozilla.org/en-US/docs/Web/API/XMLSerializer)
```javascript
serializeToString(node)
```
