1 """Core XML support for Python.

     2 

     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.
