I looked for this a while back and don't think it exists.
In the end I used the RSS option, which works well enough for me.
This is the code I used, with credit shown for the orignal author:
<?php
/*##############################################
RSS parser written for bMachine feed.
This script can be used to read ANY kind of RSS feeds from anywhere!
*--------------------------------------------*

I wrote this script on the 1st day I studied
XML by running through the documentation at www.php.net ;)
*--------------------------------------------*
WARNING!: This script is Heavily commented! :)
This is how the script works.
> Reads the XML file
> Parses it into an array using xml_parse_into_struct()
> Converts that array into a more sensible, easily usable array
[ See the structure.txt file to get an idea of the array structure ]
> Finally, Display the data in anyway you want!
This script demonstrates the use of simple logic
to do Complex XML/RSS parsing functions
This script can be easily developed into a powerful application.
