If a string value is provided, the function writes the data to the file rather than returning it.
If the filename

returns a string on success and false
on error. If the
parameter is specified, it returns true
if the file was written
successfully and false
otherwise.

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