Description

SimpleXMLElement
mixed asXML ([ string $filename ] )

The asXML method formats the parent object's data in XML version 1.0.

<?php
$string 
= <<<XML
<a>
 <b>
  <c>text</c>
  <c>stuff</c>
 </b>

 </d>
</a>
XML;

$xml = new SimpleXMLElement($string);

echo 
$xml->asXML(); // <?xml ... <a><b><c>text</c><c>stuff</c> ...

while(list( , 
$node) = each($result)) {
    echo 
$node->asXML(); // <c>text</c> and <c>stuff</c>
}
