Sorry to say so, but that's nonsense. DOM is not complicated because it
contains anything superior - the reason (if any) is that it is formulated
as language-agnostic as possible, with the unfortunate result it is rather
clumsy to use in all languages.

Additionally, it *attempts* to unify APIs in browsers, unfortunately it is
only moderately successful.

APIs such as ElementTree don't try to burden themselves with the
language-agnosticism, and thus are much more powerful.

And no, I don't think being language-agnostic is a virtue in an API. Simply
because this can never really be reached, and then is questionable anyway.
