html-parsing

问题 I am trying to parse some data from a website to get specific items from their tables. I know that any tag with the bgcolor attribute set to #ffffff or #f4f4ff is where I want to start and my actual data sits in the 2nd within that .

问题 I see this is possible using jQuery, but how can it be done in QueryPath?
