This script was originally written by Duncan Gough and his page on the rss parser can be found at: http://www.suttree.uklinux.net/code/rss/. Mr. Gough has graciously allowed me to re-release this modified version under the GPL.
This RSS parser is really cool and easy to use. That's why I like it. No muss or fuss with writing interface .php scripts, no .inc files, just add your newsfeed URL and call the script like any other SSI include.
The hack I have done on Mr. Gough's script, is one newsfeed per include, output raw text (for inclusion into your own tables) and the output will validate as W3C XHTML 1.0 Transitional. See the README for details.
