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');

?>
