Reiterating the point the blog post makes, but: It's very very easy to structure the same data in different ways in XML. While JSON has the same issue, it's a lot harder to do and you have less flexibility in making bad storage decisions.

You are absolutely right on walking the structure. JSON just tends to be easier (in my experience), even when working with XML libraries that make it less of a pain.

I'll give the opposing opinion that I find working with XML easier than JSON, but mostly because of QueryPath.
