d S )a A collection of modules for iterating through different kinds of
tree, generating tokens identical to those produced by the tokenizer
module.
To create a tree walker for a new type of tree, you need to do
implement a tree walker object (called TreeWalker by convention) that
implements a 'serialize' method taking a tree as sole argument and
returning an iterator generating tokens.

| S ) a Get a TreeWalker class for various types of tree with built-in support
Args:
treeType (str): the name of the tree type required (case-insensitive).
Supported values are:
- "dom": The xml.dom.minidom DOM implementation
- "etree": A generic walker for tree implementations exposing an
elementtree-like interface (known to work with
ElementTree, cElementTree and lxml.etree).
- "lxml": Optimized walker for lxml.etree
- "genshi": a Genshi stream
Implementation: A module implementing the tree type e.g.
xml.etree.ElementTree or cElementTree (Currently applies to the
"etree" tree type only).
