Hello Darran, building on Rik's previous answer, how about this: <dtml-call "REQUEST.set('myObjRef', _[desired_id])"> It tested OK with an Image object called "image" and located in the site root: # Storing the image name in a variable <dtml-call "REQUEST.set('desired_id','image')"> # Creating an object reference based on the variable <dtml-call "REQUEST.set('myObjRef', _[desired_id])"> # Displaying the object title and size <dtml-var "myObjRef.title"> <dtml-var "myObjRef.getSize()"> # Rendering the object if it's renderable. An image is. <dtml-var myObjRef> If it's not renderable, you'll end up with something like "<Folder instance at 01368880>" in the HTML page source code. Does it work for you? If yes, you may want to add a FAQ Question and it's Answer on zdp.zope.org (hint, hint :-). Cheers. Alexandre At 04:55 08/03/2000 -0800, you wrote:

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.
