Last November I did a presentation of the Happy Mapper fork I developed. The video is available on Vimeo. Unlike the description says, it is a fork using Nokogiri to replace XML Object, but watching it will clear everything out! It's a lightning talk, so I'm sure I won't waste too much of your time :)
You can also find all the videos from RORO on Vimeo. Enjoy!
I've updated my version of Happymapper to use Nokogiri. It should be faster. The original Happymapper had already been forked to use Nokogiri by Roland Swingler.
Nokogiri is a ruby gem to parse XML and HTML using XPath or CSS selectors. It's written mostly in C, and is very fast. I intend to use this version of Happymapper in an upcoming project with intensive parsing!
