SimpleXMLElement::asXML — Return a well-formed XML string based on SimpleXML element
说明
public SimpleXMLElement::asXML
([ string $filename
] ) : mixed
The asXML method formats the parent object's data
in XML version 1.0.
参数
filename- If specified, the function writes the data to the file rather than returning it.

If the filename isn't specified, this function
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.
范例
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 $xml->asXML();?>
以上例程会输出：
<?xml version="1.0"?> <a> <b> <c>text</c> <c>stuff</c> </b> <d> <c>code</c> </d> </a>
asXML also works on Xpath results:
Example #2 Using asXML() on SimpleXMLElement::xpath() results
<?php// Continued from example XML above./* Search for <a><b><c> */$result = $xml->xpath('/a/b/c');foreach ($result as $node) { echo $node->asXML();}?>
以上例程会输出：
<c>text</c><c>stuff</c>
