To create a treebuilder for a new type of tree, you need to do implement several things: 1) A set of classes for various types of elements: Document, Doctype, Comment, Element. These must implement the interface of _base.treebuilders.Node (although comment nodes have a different signature for their constructor, see treebuilders.etree.Comment) Textual content may also be implemented as another node type, or not, as your tree implementation requires. 2) A treebuilder object (called TreeBuilder by convention) that inherits from treebuilders._base.TreeBuilder. This has 4 required attributes: documentClass - the class to use for the bottommost node of a document elementClass - the class to use for HTML Elements commentClass - the class to use for comments doctypeClass - the class to use for doctypes It also has one required method: getDocument - Returns the root node of the complete document tree 3) If you wish to run the unit tests, you must also create a testSerializer method on your treebuilder which accepts a node and returns a string containing Node and its children serialized according to the format used in the unittests � )�absolute_import�division�unicode_literals� )� default_etreeNc K s� | j � } | t k r� | d k rl d d l m } | d k rY d d l m } | } n | j | | � j S| d k r� d d l m } | j t | <q� | d k r� d d l m } | d k r� t } n | j | | � j St d | � � n t j | � S) a� Get a TreeBuilder class for various types of tree with built-in support treeType - the name of the tree type required (case-insensitive). Supported values are: "dom" - A generic builder for DOM implementations, defaulting to a xml.dom.minidom based implementation. "etree" - A generic builder for tree implementations exposing an ElementTree-like interface, defaulting to xml.etree.cElementTree if available and xml.etree.ElementTree if not. "lxml" - A etree-based builder for lxml.etree, handling limitations of lxml's implementation. implementation - (Currently applies to the "etree" and "dom" tree types).
