My first address for RSS filtering was Yahoo Pipes! which allows one more than doing simple RSS filtering, it basically allows one to "re-wire the Web". For some reason, if I filter for blog posts associated to a certain category (e.g., computingnow) I always get zero items as shown in the figure below. Very strange as it works for other feeds but not this one. Changing the feed and/or blogging platform is not an option at the moment.
After doing the whole troubleshooting for while, it was clear that I have to search for another solution. That's why I did a Web search to find some alternatives and I found an interesting article describing six ways to filter RSS and there are even more. I tried some (e.g., Feed Rinse just produced an error when filtering for this term and FilterMyRSS works but is currently unavailable) and after some time - quite some time acutally - I wrote the following:
java -jar saxon9.jar -s:http://feeds.feedburner.com/MultimediaCommunication -xsl:rss-filter.xslt -o:public_html/ct4computingnow.xmlWell, and that's the story how this article is brought to you and the feed I've filtered myself now is available here. Of course, I could make the XSLT style sheet much more flexible by adding parameter support but that's another story...
