Meh. I just wish XML was easier to parse. I have to shuttle a lot of XML data back and forth. As far as I can tell, the only way to query the data is to download a whole engine to run a special query language, and that doesn’t really integrate into any of my workflows. JSON retains the hierarchy and is trivially parsed in almost any programming language. I bet a JSON file containing the exact same data would be much smaller also, since you don’t list each tag twice.
