This supports DOM Level 1 +       Namespaces. parsers -- Python wrappers for XML parsers (currently only supports Expat). sax -- The Simple API for XML, developed by XML-Dev, led by David       Megginson and ported to Python by Lars Marius Garshol.  This       supports the SAX 2 API. etree -- The ElementTree XML library.  This is a subset of the full       ElementTree XML release.
