  Here is the associated code. It's generated code. the xmlDoc and other
classes are wrappers for a libxml2 object and must be created with such
an object. As pointed by the working example you must use a library
call to create those objects.

class xmlDoc(xmlNode):
    def __init__(self, _obj=None):
        self._o = _obj
        xmlNode.__init__(self, _obj=_obj)

  xmlNode.__init__ could check for the type of the object an raise an
exception, that would be one way to catch those kind of mistakes.
