Nokogiri, LibXML-Ruby, REXML

I've been down the road of creating a parser for these and, in my

There are several listed at ruby-toolbox.com:

I've heard good tings about feedzirra (the top listed there) although

http://www.ruby-doc.org/stdlib/libdoc/rss/rdoc/index.html

It is essentially undocumented, but there are some examples at:
