Example #1 Get XML
<?php
$string = <<<XML
<a>
<b>
<c>text</c>
<c>stuff</c>
</b>
<d>
<c>code</c>
</d>
</a>
XML;
$xml = new SimpleXMLElement($string);
echo $xml->asXML(); // <?xml ... <a><b><c>text</c><c>stuff</c> ...
?>
asXML also works on Xpath results:
Example #2 Using asXML() on SimpleXMLElement::xpath results

// Continued from example XML above.
/* Search for <a><b><c> */
$result = $xml->xpath('/a/b/c');
while(list( , $node) = each($result)) {
echo $node->asXML(); // <c>text</c> and <c>stuff</c>
}
?>
