(no version information, might be only in CVS)

SimpleXMLElement->xpath -- Runs Xpath query on XML data.

## Description

array SimpleXMLElement->xpath ( string path)

The xpath method searches the SimpleXML node for children matching the Xpath path. It always returns an array of SimpleXMLElement objects.

示範 1.Xpath
`<?php $string = <<<XML <a> <b> <c>text</c> <c>stuff</c> </b> <d> <c>code</c> </d> </a> XML; $xml = simplexml_load_string($string); /* Search for <a><b><c> */ $result = $xml->xpath('/a/b/c'); while(list( , $node) = each($result)) { echo '/a/b/c: ',$node,"\n"; } /* Relative paths also work... */ $result = $xml->xpath('b/c'); while(list( , $node) = each($result)) { echo 'b/c: ',$node,"\n"; } ?>`
This script will display:
    /a/b/c: text
    /a/b/c: stuff
    b/c: text
    b/c: stuff
Notice that the two results are equal.
