I don't see a problem here. When you want something that is short,
because you use it *all* *the* *time*, then you won't forget how it
works. What's the difference between remembering that [index] gives
you the index'th child and remembering that _get_childNodes(index)
does it?

And the implementation is straightforward:

         def __getitem__(self,index):
                 if type(index) =3D=3D types.IntType:
                         return self._get_childNodes(index)
                 elif type(index) =3D=3D types.StringType:
                         return self._get_attribute(index)
                 else:
                         raise ValueError("wrong type for index")

(or whatever the DOM API will be)
