Humans (which includes many developers) preferprettier printthan what was just shown for the generated JSON. I've seen a fair share of ungainly XML->JSON code on the web, and having interacted with Stack's users for a bit, I'm convinced that this crowd can help more than the first few pages of Google results can. When I run the demonstration class again with this modified method, the JSON output is more aesthetically pleasing: I have been using Jackson 2.5.4 in this post. There is no mapping back to XML to get an identical document, the reason is, it is unknown whether a key/value pair was an attribute or an value, therefore that information is lost.
