What is pygixml and how do I install it?

pip install pygixml—430KB, no deps. Parses via pugixml C++ for max speed.

Is pygixml faster than lxml for XML parsing?

Yes, 4.5x on parse time here, 12x smaller package. Both low-mem; pygixml wins footprint.

8.6x faster parse, 7x less memory on 5K nodes. Repro code on GitHub.

XML's not dead—it's just slow in Python. pygixml changes that with pugixml's raw speed, slashing parse times to 0.9ms and memory by 7x.
