"""W3C Document Object Model implementation for Python.
|
||
|
|
|
||
|
|
The Python mapping of the Document Object Model is documented in the
|
||
|
|
Python Library Reference in the section on the xml.dom package.
|
||
|
|
|
||
|
|
This package contains the following modules:
|
||
|
|
|
||
|
|
minidom -- A simple implementation of the Level 1 DOM with namespace
|
||
|
|
support added (based on the Level 2 specification) and other
|
||
|
|
minor Level 2 functionality.
|
||
|
|
|
||
|
|
pulldom -- DOM builder supporting on-demand tree-building for selected
|
||
|
|
subtrees of the document.
