Subject: [PATCH] Tester for loading document in XML format

Inspired by the fact that SVG and HTML are XML and I was trying to write about them in the Literature Notes.

The pugixml library for C++ seems actually usable.
Could do a number of fancy things using it, but really should get back to that Literature Review :S
