Can't start django 1.11.3 application after python3.6 upgrade

[DanBuchan]

python 3.6
Django 1.11.3
djangorestframework 3.6.3
djangorestframework-xml 1.3.0

Starting application returns:
ImportError: Could not import 'rest_framework_xml.parsers.XMLParser' for API setting 'DEFAULT_PARSER_CLASSES'. AttributeError: module 'xml.etree.ElementTree' has no attribute '_IterParseIterator'.

Have tried djangorestframework-xml 1.4.0 and all version of djangorestframework from 3.6.3 to 3.9.0

That error sounds pretty similar to tiran/defusedxml#3, have you tried upgrading your defusedxml version?

My temporary (and ongoing) workaround was to comment out XMLParser support but I will look in to your suggestion when I get a moment.
