requests_xml seems to return XML with namespaces without issue. However, unless I've missed something, it doesn't appear there is a way to pass a XML NSMAP variable through requests_xml so that you can easily access XML with namespaces using XPATH.
For the instances where I'm forced to use XML namespaces, I've had to revert back to using lxml/etree. Would be be possible to add the NSMAP functionality to the top level requests_xml functions so that the XML namespace mapping is properly passed down to the lxml functions used under-the-hood?
