What I would like to do is the inverse of this; I want to use iTunes, or something as flexible as iTunes, to view any old XML. (an old iTunes exported library would be a start.

I have searched for any xml parser out there that is as elegant as iTunes, and even asked people that provide a load of XML content on their site what they recommend, and they merely say "There's Tons of them, take a look". Umm, is that begging the question?

What I want is something that will view any xml file in column form, allow the columns to collapse or sort, and allow that spotlight style searching of the contents. Without having to dealing directly with PHP and the terminal.
