[docs]class Node(StringMixIn): """Represents the base Node type, demonstrating the methods to override. :meth:`__str__` must be overridden. It should return a ``str`` representation of the node. If the node contains :class:`.Wikicode` objects inside of it, :meth:`__children__` should be a generator that iterates over them. If the node is printable (shown when the page is rendered), :meth:`__strip__` should return its printable version, stripping out any formatting marks. It does not have to return a string, but something that can be converted to a string with ``str()``. Finally, :meth:`__showtree__` can be overridden to build a nice tree representation of the node, if desired, for :meth:`~.Wikicode.get_tree`.
