## groovy.util
Class XmlSlurper

    java.lang.Object
      org.xml.sax.helpers.DefaultHandler
          groovy.util.XmlSlurper

All Implemented Interfaces:
  ContentHandler, DTDHandler, EntityResolver, ErrorHandler

    public class XmlSlurper
    extends DefaultHandler

Parse XML into a document tree that may be traversed similar to XPath expressions. For example:

     def rootNode = new XmlSlurper().parseText(
        '<root><one a1="uno!"/><two>Some text!</two></root>' )

     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'] }

Note that in some cases, a 'selector' expression may not resolve to a single node. For example:

     def rootNode = new XmlSlurper().parseText(
        '''<root>
             <a>one!</a>
             <a>two!</a>
           </root>''' )

     assert rootNode.a.size() == 2
     rootNode.a.each { assert it.text() in ['one!','two!'] }
