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');

?>
