-:mod:`xml.dom.minidom` is a light-weight implementation of the Document Object
-Model interface.  It is intended to be simpler than the full DOM and also
-significantly smaller.

-
-   The :mod:`xml.dom.minidom` module provides an implementation of the W3C-DOM,
-   with an API similar to that in other programming languages.  Users who are
-   unfamiliar with the W3C-DOM interface or who would like to write less code
-   for processing XML files should consider using the
-   :mod:`xml.etree.ElementTree` module instead.

 DOM applications typically start by parsing some XML into a DOM.  With
 :mod:`xml.dom.minidom`, this is done through the parse functions::
 
    from xml.dom.minidom import parse, parseString
 
    dom1 = parse('c:\\temp\\mydata.xml') # parse an XML file by name
 
    datasource = open('c:\\temp\\mydata.xml')
    dom2 = parse(datasource)   # parse an open file

 .. [#] The encoding name included in the XML output should conform to
    the appropriate standards. For example, "UTF-8" is valid, but
    "UTF8" is not valid in an XML document's declaration, even though
    Python accepts it as an encoding name.
