This is great thank you. Definitely helps clear things up a bit. So
it's not just me... Hpricot has a few bugs that have been around for a
while. That's too bad :(

OK, for a quick Nokogiri question... is it possible to ask a node if
it responds to a certain xpath? Something like:

matching = nodes.select{|n| n.is_findable_by('[@class=plant]') }

Thanks,
Matt
