This doesn't necessarily answer the question, but I imagine you'd be much better off using the Facebook api for this sort of thing. There also seems to be a few gems for working with the Graph API. To answer your question, I and others have run into issues with parsing complex tables and there are some strategies for dealing with that such as here<http://zeljkofilipin.com/watir-nokogiri/> .
