there are many variations and combined functionality that we can do
with these dicts with attribute like functionality... below is an
example of one that lets you do the dot thing on copies of a dict
(comes in vary handy at times) and uses cPickle (can send usage if
unclear)
something else very useful, is the ability to take an xml doc and
convert that to these dicts, makes handling xml and dict seamless. can
convert from xml to dict like object, or normal dict types, or any of
these combinations. WOuld have posted it, but its a little big and I
don;t seem to understand how to add an attachement to these posts. But
will gladly email if anyone is interested.
