Filtering Rss Feed

Apr 5, 2010 at 8:30 PM

Apology if there is already a post on the subject. I am using a feed reader component in sharePoint to display news from my blog. The way it works,  I enter the URL path to the feed to display all news. Is there a way to filter the news by categories in the URL?  I tried for example this It is still returning all the news.

Thank you.
