Why XML and JSON? Before XML arrived, I wrote software to import data stored in an undocumented binary format. I used a debugger to identify data field types, file offsets, and lengths.

My last article, “Java XML and JSON: Document processing for Java SE, Part 1” introduced a variety of document transformation and processing techniques using SAXON and Jackson.

You're supposed to be either on the XML side or the JSON side of the debate. But I keep reading XML while writing JSON. Am I a bad person?
