XMLDiff\DOM can be use like this, for compare xml files changes.

<?php


function getChangeElements($currentContent, $oldContent) {
try {
$currentDoc = new DOMDocument();
$currentDoc->loadXML($currentContent);

$oldDoc = new DOMDocument();
$oldDoc->loadXML($oldContent);
$xmldiff = new XMLDiff\DOM();
return
$xmldiff->diff($oldDoc, $currentDoc);
} catch (
Exception $ex) {
throw
$ex;
}
}

getChangeElements('updated.xml', 'old.xml');

?>
