   3 This package contains four sub-packages:
   4
   5 dom -- The W3C Document Object Model.  This supports DOM Level 1 +
   6        Namespaces.
   7
   8 parsers -- Python wrappers for XML parsers (currently only supports Expat).
   9
  10 sax -- The Simple API for XML, developed by XML-Dev, led by David
  11        Megginson and ported to Python by Lars Marius Garshol.  This
  12        supports the SAX 2 API.
  13
  14 etree -- The ElementTree XML library.  This is a subset of the full
  15        ElementTree XML release.
