[support] Quick module question: filtered / regex'd RSS feeds?

[Chris Johnson]

Is there a module out there that will let me aggregate or display an RSS feed 
on my site which will only use items in that RSS feed which match some sort of 
regular expression or other filtering criteria?  I don't want to display all 
of the items in the feed, only those 10% or so that match my desired topics.

Thanks,
