[b]"What's the best way to parse and manipulate XML in Python?"[/b] or [b]"How do you handle XML data efficiently

lxml is my go-to for python xml stuff. Way faster than ElementTree and handles namespaces better.

For large files, stream with `lxml.etree.iterparse()` and clean up as you go.

Namespaces? Just ignore ’em if you can (lol), or use `lxml`’s `nsmap`.

Also, `xmltodict` is neat if you wanna work with dicts instead of nodes.
