How do I join two or more Wordpress RSS Feeds?

Question

I have two Wordpress blogs installed separately and I want to join its RSS Feeds into one.

I've found this way: http://theos.in/technology/howto-combine-two-wordpress-rss-feed/ and it works but it's too slow to use.

There is a simple and fast way to do it?

Answer 1

I've used Yahoo Pipes as a way to do this. In short, you can mashup several feeds into a single one. They have a short tutorial and it's pretty easy to use.

Answer 2

I've found a good solution!

The script was running slow because I wasn't using cache correctly. You can set a cache timeout to use the generated Feed RSS in Feed Creator. You just have to set the same parameters for saveFeed...

$rss->saveFeed("RSS2.0", $TMP_ROOT."/rsscache/feed.xml");

... on useCached

$rss->useCached("RSS2.0", $TMP_ROOT."/rsscache/feed.xml", 3600); //1 hour reload

Then you call useCached before start creating a new version of that RSS Feed.
