It extends the ElementTree API significantly to offer support for XPath, RelaxNG, XML Schema, XSLT, C14N and much more.

Features added

Bugs fixed

  • XMLID() function was missing the optional parser and base_url parameters.

  • Searching for wildcard tags in iterparse() was broken in Py3.

  • lxml.html.open_in_browser() didn’t work in Python 3 due to the use of os.tempnam. It now takes an optional ‘encoding’ parameter.
