Combining and filtering RSS feeds with Yahoo! Pipes
First published on January 12, 2008
I write for another blog as well, and wanted to create a combined RSS feed of my posts on that blog and this one. I discovered that the easiest, and quickest way to do this is with Yahoo! Pipes, which describes itself as “a powerful composition tool to aggregate, manipulate, and mashup content from around the web.” Browsing through the existing “pipes” that people have made, it does quite a lot of cool and innovative stuff. To me, it’s simply a great service that offers a very intuitive interface that enabled me to combine RSS feeds!
The interface has a bunch of elements:
It looks rather technical, but I was able to very quickly find which elements I needed. These elements can be dragged and dropped into the work area and then connected in an intuitive workflow:
For example, I had a source element that fetched my two RSS feeds. These feeds were are piped into the sort operator and combined so that the feed items are sorted in descending order. Then, the results of that are filtered to show only the posts that I have written (since the other blog is a group blog). Poof, the output is piped out and into a nice RSS feed. I can even “burn” this feed on Feedburner without anybody knowing how easy it all was…
