Seeking a PHP script to filter an RSS feed

Question

I have about 50 feeds (and growing) that I would like to filter before adding them to Google Reader. Each of the feeds will be filtered for the same keywords. If a keyword match is found, that item will be removed from the feed. Basically I'm just trying to eliminate some noise.

I know I can do this with Yahoo Pipes, but I'm looking for a self-hosted solution.

I'd like to pass a feed to a script on my server. That script will filter out unwanted feed items based on a list of defined keywords. The filtered feed will be the result. I plan to then add the feed to Google Reader.

(BTW, why doesn't Google Reader have filters like Gmail?)

Answer 1

Try using a RSS library like Simplepie. From there, writing the filter logic should be easy-peasy.

Answer 2

Try ReFilter. Looks nice.
