    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;
    }
    }
