Hello!

Using php5+ you can make use of the XPath section of the domxml extension.

http://uk3.php.net/domxml - for the extension overview.

Searching is described here

http://uk3.php.net/manual/en/function.xpath-eval-expression.php

The php manual documentation is not that great for this extension, I
would recommend buying "Upgrading to PHP5" which I think covers the new
PHP 5 XML functions very well.
