Any examples of a LUA script for XML?

edit

Hey all - I'm trying to get started writing my first LUA dissector to decode the MOS protocol http://mosprotocol.com/wp-content/MOS...

Before I overcommit myself, can anyone point me in the direction of a LUA dissector that already handles XML? I'm just starting my field definitions now, and thought I should probably ask before I get too deep down the rabbit hole.

Many thanks

Scott
