Выше данные сохраняются в одной переменной: - 

$xml = simplexml_load_string($xmlstring, "SimpleXMLElement", LIBXML_NOCDATA);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
echo "<pre>"; print_r($array); die;

Существует узел RETVAL, я хочу получить все данные json из этого узлаи преобразовать в массив.Я пробовал приведенный выше код, но не работает.Может кто-нибудь помочь мне, как решить эту проблему, спасибо заранее.

Вам необходимо получить значение узла, который содержит вашу строку JSON.Я бы использовал DOMDocument и DOMXPath , чтобы сделать это: 

<?php

$xmlString = <<<END
