Can anyone please help me how can i do this ?

What do you expect the result to be like (You can miss out most of the XML if this is just copied, but show how the elements should be layered) — Nigel Ren

IMHO - the best way to do this is to import the XML into DOM which allows you more flexible ways of adding nodes and moving them around.

This code loads the access request as the start of the DOM document and then imports the second XML as a new node, it then appends it to the end of the existing XML...

$dom = new DOMDocument();
$dom->loadXML($accessRequestXML->asXML());
$importrr = dom_import_simplexml($rateRequestXml);
$domImportRR = $dom->importNode($importrr, true);
$dom->documentElement->appendChild($domImportRR);
echo $dom->saveXML();
