[Zope] Drilling into second-level object properties

[Dan Shafer]

This may just be a case of over-engineering. But I'd like to see if I 
can learn how to fix this anyway.

I have a Zope application. When using it, people we call facilitators 
create a new folder for a particular client interaction. Then as they 
progress through the structured interaction, each phase creates a new 
document whose only contents are a call to a DTML method that displays 
objects' contents. Each of these documents has a set of properties 
associated with it.

So the structure is:

Folder
   Document (with properties)
     <dtml method call>

Now, I need to write a routine that iterates over all the folders in a 
given directory, examines the document called [caseID]info to determine 
if one of its properties (coach_id) matches the name of the currently 
AUTHENTICATED_USER. If so, display the folder as an HREF (that I have 
working fine) and if not, skip it.

I keep running into syntactical issues. Dylan Reinhardt has already 
switched me on  to the nearly undocumented prefix attribute of the 
dtml-in construct, so I've at least gotten past that problem. But 
drilling down another level in the object hierarchy is proving 
syntactically...well...challenging.

Anyone got any ideas?

Thanks.
