RSS reader

filter by keyword

[jornada11]

Can anyone tell me of an RSS reader that allows a real-time, saved keyword filter at the feed level?

For example, I want the feed to update, automatically, only stories with the term "webmasterworld" in it but ONLY from the Search Engine Watch Daily RSS. So every time a story on that feed contains that keyword, it shows up. I want to be able to save this so that the only stories I get from SEW daily contain webmasterworld.

thanks...
