XmlParser (groovy 3.0.6 API)

groovy.util.XmlParser

All Implemented Interfaces and Traits:

ContentHandler
```
@Deprecated
public class XmlParser
extends Object
implements ContentHandler
```
A helper class for parsing XML into a tree of Node instances for a simple way of processing XML. This parser does not preserve the XML InfoSet - if that's what you need try using W3C DOM, dom4j, JDOM, XOM etc. This parser ignores comments and processing instructions and converts the XML into a Node for each element in the XML with attributes and child Nodes and Strings. This simple model is sufficient for most simple use cases of processing XML.
Example usage:
```
 def xml = '<root><one a1="uno!"/><two>Some text!</two></root>'
 def rootNode = new XmlParser().parseText(xml)
 assert rootNode.name() == 'root'
 assert rootNode.one[0].@a1 == 'uno!'
 assert rootNode.two.text() == 'Some text!'
 rootNode.children().each { assert it.name() in ['one','two'] }
 
```
