PHP and XML: using expat

[artoo]

I was following the code at www.phpbuilder.com/columns/justin20000428.php3 and can't figure out how to parse the URL tag of the XML statement

<TITLE>PHP</TITLE><URL>www.php.net</URL>

so that the tile is printed between the > and </a> statments resulting in the HTML code <a href="http://www.php.net">PHP</a>

I'm guessing that I have to do write code to handle the URL tags but I'm not sure which functions I have to change.

Thanks for any help.
