You can also implement the special methods __getitem__ and __setitem__
to allow indexed access to attributes, ie:
class FalseDict(object):
def __init__(self, toto, tata):
self.toto = toto
self.tata = tata
def __getitem__(self, name):
return getattr(self, name)
def __setitem__(self, name, value):
setattr(self, name, value)
f = FalseDict('toto', 'tata')
f['toto']
f['tata'] = 42

Don't reinvent the wheel. ElementTree (and it's C based brother) are
very good at this.
