3 �Re � @ s6 d Z ddlmZmZmZ ddlmZ i Zddd�ZdS ) a) A collection of modules for building different kinds of trees from HTML documents. 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 � } | tkr�| dkrLddlm} |dkr<ddlm} |}|j|f|�jS | dkrlddlm} |jt| < n<| d kr�dd lm } |dkr�t }|j |f|�jS t d | ��tj | �S ) a Get a TreeBuilder class for various types of trees with built-in support :arg 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. :arg implementation: (Currently applies to the "etree" and "dom" tree types). A module implementing the tree type e.g. xml.etree.ElementTree or xml.etree.cElementTree. :arg kwargs: Any additional options to pass to the TreeBuilder when creating it.
