The other month we hooked Dave's commit2rss.rb script up
to our CVS repository to gain an RSS feed. (Thanks Dave!)
Now we'd like to display the RSS feed in a sidebar. What's
the best method to do this? Currently our web person is
using some third-party converter that produces some rather
ugly HTML.
My Dr Dobbs article has a trivial program to do exactly that.
Here's a variant of it that we use on the PragProg site to create some
HTML which is injected into Mike Clark's automation page. It reads his
blog's RSS, then uploads a converted file to our website.
Cheers
Dave
