Yes.

include_match %r{} should work.

I believe HTree is some sort of wrapper around REXML::Document, or at  
the very least forwards its messages on to that.

document.elements[XPATH] fetches a single element. You want  
document.get_elements[XPATH] to fetch all, or (and this should be a  
little faster) document.each_element(XPATH) { |e| } or  
document.elements.each(XPATH) { |e| }.
