Will use this variant.

But that would have been soo cool... :)

Ah, I see.

Oops...

Hmm, that doesn't quite fit.  How would you like to have the following
construct splitted?

        foo = getElementsByName(
            getElementByName(getElementByName(getElementByName(
            root, 'Capability'), 'Request'), 'GetMap'), 'Format')

It could be done with a *long* root.foo.bar[0].baz[1].gnarz... chain as well.

I don't want to assign four local variables just to keep all
constructs short.
