## [Java] Class XmlSlurper

- groovy.util.XmlSlurper

-     @Deprecated
      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!'] }

    use XmlSlurper
