Lxml

June-19-16 

Powerful and Pythonic XML processing library combining libxml2/libxslt with the ElementTree API. 

…is a pain to install on Windows. By default it tries to compile form source. There are binaries, but they don't track the current python release all the time.

https://pypi.python.org/pypi/lxml 

Find current release and identify what versions of python it supports, install that version of python, and then binary xml installer.

Pip only seems to do the right thing for lxml when installing from a wheel.
