Compressed JSON perhaps but console.log it and the console formats it into a treelike structure that i think is fine to read... I'm not suggesting we forget xml altogether just think we should think about our target audience - mobile devices instigated the transition to html5 but these 2 equations generally hold up in the mobile field

extra processing = less battery time
more bandwidth use = more money

Should we have these two areas in our sights by minifying files, using cdn where available and using the most appropriate data formats?

But I like the human readable structure xml gives you: it's not so easy to eyeball json for a particular thing.

My vote would be to stick with XML.... Even if it's a little slower.
Internally we could work with json, no problem. Then, in the conversion from xml to json, do whatever is needed for the tree view.

The other problem, if I recall, was that the ones that used XML needed the nodes to be a named a certain way, and again if I remember right, there wasn't one that could take *any* xml as a data provider.
