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

$xml = new SimpleXMLElement($string);
echo $xml->asXML();
?>

<?xml version="1.0"?> <a> <b> <c>text</c> <c>stuff</c> </b> <d> <c>code</c> </d> </a>
asXML also works on Xpath results:
Example #2 Using asXML() on SimpleXMLElement::xpath() results
<?php
// Continued from example XML above.
/* Search for <a><b><c> */
$result = $xml->xpath('/a/b/c');
while(list( , $node) = each($result)) {
echo $node->asXML();
}
?>
The above example will output:
<c>text</c><c>stuff</c>
