# simplexml_element->xpath

(no version information, might be only in CVS)

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

## Description

array simplexml_element->xpath ( string path)

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

Przykład 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.
