Here's an example that works with my blogger site feed: http://wizzodawg.blogspot.com/feeds/posts/default 

It's simple, but gives you an idea of what's involved.  It does not include all of the namespaces in the feed, but is actually one that I worked on as an 'All-In-One' type of xsl that I use for a lot of differ rss newsources.  You can modify it and play with it.  Of course, it may not work for you depending on the URL and feed you are using, but if you have facility with RSS and XSL, it should get you on the way.

Cheers
