new xml library? #619
Description
we currently use:
emeraldtree- was forked from elementtree and adapted for moin2 to overcome some lacking API of elementtree back then
- https://pypi.org/project/emeraldtree/
- https://libraries.io/pypi/emeraldtree (looks like only moin2 is using this)
- mostly unmaintained
- lacks xpath support
- py27 and py33, pure python
lxml- https://pypi.org/project/lxml/
- maintained and lots of users
- was sometimes painful to install in the past (current state == ?)
- xpath support (this is why we use
lxml.etreefor our tests already) - py27 and up to py37, pypy support == ?
there is also elementtree in python stdlib, which got limited xpath support.
