Subject: Tester for loading document in XML format
X-Git-Url: https://git.ucc.asn.au/?a=commitdiff_plain;h=bf0f1cab25fa460ad4716ca60c11abab78a52cbd;p=ipdf%2Fcode.git

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
