Yes, this is what I was looking for. What I think is missing is a method to
construct the full query path, so that you don't have to code for "item" and
"title" , something like pt.get_match("rss.channel.item.title") . Also, the
fact that it preserves the ordering is important (and performance is less
important in this case)
