-"""Lightweight XML support for Python.
-
- XML is an inherently hierarchical data format, and the most natural way to
- represent it is with a tree.  This module has two classes for this purpose:
-
-    1. ElementTree represents the whole XML document as a tree and
-
-    2. Element represents a single node in this tree.
-
- Interactions with the whole document (reading and writing to/from files) are
- usually done on the ElementTree level.  Interactions with a single XML element
- and its sub-elements are done on the Element level.
-
- Element is a flexible container object designed to store hierarchical data
- structures in memory. It can be described as a cross between a list and a
- dictionary.  Each Element has a number of properties associated with it:
-
-    'tag' - a string containing the element's name.
-
-    'attributes' - a Python dictionary storing the element's attributes.
-
-    'text' - a string containing the element's text content.
-
-    'tail' - an optional string containing text after the element's end tag.
-
-    And a number of child elements stored in a Python sequence.
-
- To create an element instance, use the Element constructor,
- or the SubElement factory function.
-
- You can also use the ElementTree class to wrap an element structure
- and convert it to and from XML.
