Using Yahoo Pipes to Filter Results for Iterasi PositivePress

I’ve been beta testing Iterasi’s PositivePress for a while and was excited to finally see it released to the public! It’s a great way to track and archive blog posts and articles from across the web while creating reports with links to certain articles that can be delivered to clients or friends. CNET did a great job of covering the release, so I won’t rehash it here. I encourage you to read the CNET article for more information about PositivePress.

Since PositivePress uses RSS feeds as input, I decided to do a quick video showing you how to use Yahoo Pipes to filter results from your RSS feed to make sure that you are only archiving and reporting on the most relevant results. This video shows you how to take a list of feeds from a CSV file, fetch the results, and filter them for a set of keywords. The end result is fed into PositivePress and a new report is generated from the filtered results.

If you haven’t already watched the rest of the Yahoo Pipes Video series, you might benefit from watching these other videos first. They provide a little more background on the concepts used in this Yahoo Pipe.

This Yahoo Pipes video series is also available as a podcast on iTunes, and as a separate feed.

You can watch the embedded video above, but I recommend downloading the higher resolution Quicktime file (30 MB) to watch. The quality will be much better than the flash version above.

More Details on the Pipe:

  • The Demo Pipe. A copy of the Using Yahoo Pipes with Iterasi PositivePress pipe click “View Source” to see the modules.
  • Fetch CSV Module. Enter the URL of a CSV file. Here is the example we used in the video.
  • Loop module with Fetch Feed. Loops through each element in the CSV file and fetches the feed associated with the item.
  • Filter Module (Permit). Filter by a couple of keywords to permit only the results that match at least one of your keywords
  • Filter Module (Block). Filter out any results that match undesired keywords.
  • Sort Module. Sort by date in descending order to make sure things are sorted in a logical manner.
  • Pipe Output. The final module in every Yahoo Pipe.

I’ve created many Yahoo Pipes, and most of them have been published on my Yahoo Pipes and RSS Hacks page where you can also learn more about my Yahoo Pipes Training courses.
