QGIS server WFS response not parsed by OWSLib

Original Redmine Issue: 14250
Affected QGIS version: 2.8.5
Redmine category:qgis_server
Assignee: René-Luc ReLuc

We have had to resort to parsing WFS XML responses since there seems to be some keyword case sensitivity in either QGIS server or OWSLib that's preventing unfettered OGC communication.

I wasn't able to diagnose if the problem is with QGIS or OWSLib

It would be much easier to analyze if the XML from QGIS server is valid if you could add a sample.

GetCapabilities XML attached.

By the way, this is the response when I try to use OWSLib:
Based on the documentation, they have three WFS versions supported:

Version 1.0.0

QGIS Server only provides WFS version 1.0.0.

It seems that OWSLib is waiting for Keywords in capabilities.
