[QGIS-Developer] PyQt QtXmlPatters and QXmlQuery ?

[Richard Duivenvoorde]

Hi,

Trying to port a plugin here from py2 to py3 the devs have used:

from PyQt4.QtXmlPatterns import QXmlQuery
then use:
QXmlQuery(QXmlQuery.XSLT20)

but.. in QGIS3 we tried to get rid of Qt-version dependency, so we encourage to use
from qgis.PyQt.QtCore import xxxx
etc

but (looking into my installs and trying in the python console

from qgis.PyQt.QtXmlPatterns import QXmlQuery
returns me a 
ModuleNotFoundError: No module named 'qgis.PyQt.QtXmlPatterns'

BUT: if I do 

from PyQt5.QtXmlPatterns import QXmlQuery
the class is successfully loaded

Should/Can I include QtXmlPatterns.py here:

https://github.com/qgis/QGIS/tree/master/python/PyQt/PyQt5

without issues? Or am I creating a new dependency then?

Regards,

Richard Duivenvoorde
