Your example shows why XML parsing is so strict. If I add your example into my XQuery processor, I get: "Different start and end tag: <i>...</b>." Also, HTML != XML.

Also, with JsonML there is a lossless mapping from XML to (array based) JSON (and vice versa), which makes the project linked here, totally redundant.
