use groovy.xml.XmlSlurper

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!'] }
