I've spent the day trying to process variours RSS feeds using XSLT and
pretty much decided it's not worth it...  Some feeds are ok, some
contain escaped markup and other contain a mix of escaped and
non-escaped markup, cdata sections etc

Has anyone done this already?    Any thoughts on processing RSS with
xslt in general?

The 're-feeds' | collators  do it far better than I can.
I got to about 15 'specials' before I gave up.
That was atom/rss (4 versions) etc.
