Good tutorial on XML/XSL/RSS

Hi all,

I am web manager for a number of large government websites. I am trying to
get up to speed on content syndication using RSS news feeds and XSL
reformatting. All the tutorials I can find on the web seem to be extremely
vague - almost as if they were written by people who understand the
technology but really have no idea what to use it for.... especially the W3C
tutorial.

Has anyone come across a really good, down to earth tutorial that teaches
you what XML/XSL can really do and the scope of uses for RSS news feeds? I
can learn to code it later, once I know what I want to do with it....
