Theoretically, .toxml('us-ascii') should generate usable output. 
Unfortunately minidom doesn't really do this properly and you'll get a 

As a workaround you could just take the UTF-8 encoded version and 
.encode('us-ascii', 'xmlcharrefreplace') on it... which is technically 
the wrong thing if nodeNames or CDATASections or whatever have non-ASCII 
characters in, but that probably doesn't matter to you.

ObStandardPlug: pxdom supports both proper charref-escaping (using 
DOM3LS DOMOutput.encoding) and keeping EntityReference nodes (using 
DOM3Core DOMConfiguration.setParameter('entities', True) or 
pxdom.parse(file, {'entities': True}).)
