Well, that's a bit of a pathological case in general.  In this
particular case I'd probably write a function or method to combine those
nested getElementByName calls, e.g.

def getNestedElementsByName(element, *names):
    for name in names:
        element = getElementByName(element, name):
    return element

And then you can do

foo = getNestedElementsByName(root, 'Capability', 'Request', 'GetMap', 
                              'Format')

Or you could extend getElementByName to accept more than one name.

Well, sometimes it's easier to read if you introduce a new variable,
sometimes not.  I don't want to create rules that handle all of the
possible situations.  Not least because I wouldn't always abide by them
:)
