Romain Francoise mentions Yahoo Pipes

.

Well, I played with Yahoo pipes like one or two weeks ago; and while I was impressed with their Visio-Like UI, I was lacking pretty much all functionality I wanted to try…

My goal was simple: run a query on Google Blog Search (which will have the result available in RSS), and then grab all URLs out of that stream.

But I didn’t find any ‘filter’ in Yahoo Pipes which allowed me to extract the URLs (or any part of the text, actually) from the blog entries. I don’t want to remove whole result entries, but I just want to extract certain text chunks from their body… (there might be multiple, so the regexp module isn’t an option either).

I could do that with Python in a few lines, actually.
