[Zope] getting object reference from an id string?

Say one has an object reference and knows the string id of a child node. From this info, we want an object reference to the named child. I'd like someone to prove me wrong that there is not a one-liner to accomplish this seemingly trivial task. I've had to resort to (off the top of my head) code like: <dtml-in "objectValues(['child meta-type'])"> <dtml-with sequence-item> <dtml-if "id == desired_id"> <dtml-call "REQUEST.set('desired_ref',_['sequence-item'])"> </dtml-if> </dtml-with> </dtml-in> I'm really looking for a solution that doesn't require looping. Since Zope enforces unique id's at a given level, the name should be sufficient to resolve the child object. Darran.
