On [[LINK href="http://codewi.se/"]]Codewi.se[[/LINK]] we grab RSS feeds and show the results. But what about when I want to take several RSS feeds and combine it into one display, with all the different items, from RSS feed, being intermingled based on their date? Is there a plugin for that?
Ivaylo Draganov answers:
You could use Yahoo Pipes or another similar tool to stitch the feeds together (at the same time ordering by date, trimming and so on). Or you could use the SimplePie library that's included with WordPress - it can also process multiple feeds.
I'm not sure whether there's a plugin for that. I've written a function that I use with SimplePie on a couple of sites. It's based around this:
I think you can pass it an array of feed URLs. You'd have to dig into SimplePie's documentation though and adapt the function's output and parameters to suit your needs.

I do the same on [[LINK href="http://centipiet.com"]]this site[[/LINK]]. To accomplish this I use the [[LINK href="http://wordpress.org/extend/plugins/feedwordpress/"]]FeedWordPress[[/LINK]] plugin in combination with earlier mentioned Yahoo Pipes.
