4. Automation > Interact with RSS Feeds

Interact with RSS Feeds

Yahoo! has a service (currently and perpetually in beta) called Pipes. The Pipes service allows you to manipulate RSS feeds (like blogs), combining, filtering, and processing the results to create either a web page result or another RSS feed. It uses a web-based drag-and-drop interface to create “pipes” from one feed to another, borrowing the Unix command-line pipe metaphor. From a usability standpoint, it looks much like Mac OS X Automator, where each of the commands (or pipe stages) produces output to be consumed by the next pipe in line.

For example, the pipe shown in Figure 4-1 fetches the blog aggregator from the No Fluff, Just Stuff conference site that includes recent blog postings. The blog postings occur in the form of “blog author - blog title,” but I want only the author in the output, so I use the regex pipe to replace the author-title with just the author’s name.
