Compare 2 XML Skeletons Issue

I am facing an issue comparing two xml's ignoring text and attribute values. (My requirement is just to compare the Skeleton(elements and attributes) but not the text and values)

Here is the Code I have. Please Help.


Code:

import groovy.io.FileType
import org.custommonkey.xmlunit.*

def diff = new Diff("<location><street-address>22 any street</street-address><postcode>XY00 99Z</postcode></location>",
"<location><street-address>20 east cheap</street-address><postcode>EC3M 1EB</postcode><country></country></location>")

DifferenceListener myDifferenceListener = new IgnoreTextAndAttributeValuesDifferenceListener()
diff.overrideDifferenceListener(myDifferenceListener)

if(!diff.identical()) {
log.info'Files are Different'

def detailedDef = new DetailedDiff(diff)
def defferences = detailedDef.getAllDifferences()
//Build Text Report
buildDiffs(defferences)
} else {
log.info 'Files are Identical'
}


def buildDiffs( differences){
differences.each { nodeDiff ->
log.info nodeDiff.toString() + '<br>'
}
}


Actual Output:


Mon Nov 11 18:43:30 EST 2013:INFO:Expected number of child nodes '2' but was '3' - comparing <location...> at /location[1] to <location...> at /location[1]<br>

Expected Output:
