Possible bug parse_xml and parse_cli in documentation

[cobradivisor]

Before I open a bug report, my project uses the filter parse_xml. With the latest release of ansible.netcommon 5.2.0 parse_xml no longer works. I discovered if I change the following line in plugin_xml documentation it all works

ansible.netcommon/plugins/filter/parse_xml.py

Line 39 in 3b50805

type: string

from type: string to type: str

Is there a package I need to update that will also allow keyword string.
