search for: as_rexml_document

Hi, I need to do some screen scraping and I''ve spent a couple hour getting htmltools and rexml do the right thing. Here''s the code: parser = HTMLTree::Parser.new(false, false) parser.feed(res.body) tree = parser.tree.html_node.as_rexml_document I works for one page, but for another I get "undefined method `add'' for #<HTMLTree::Element:0x37f9cc8>" in as_rexml_document It seems like a library mismatch, but I just downloaded ruby and all the libraries in the past couple days. Does anybody know what versions I need...
