[Zope] DTML-IN only over special documents??

[Casey Duncan]

dtml in does not have a built in facility to filter this way, but you 
can write a short python script that returns a list of objects named a 
certain way:

docs = []
for id in context.objectIds('DTML Document'):
     if id.startswith('mydoc'):
         docs.append(context[id])
return docs

If you call this getDocs, you could use it in dtml like so:

<dtml-in expr="Folder.getDocs()">
...
</dtml-in>

Just put getDocs somewhere where Folder can acquire it. Or if you want 
to squirrel it away somewhere (like in a "scripts" folder), add an 
parameter to the script so you can pass it the folder to look in. You 
could also add parameters for the meta-type and name to look for to make 
it more generic.

BTW: The above code assumes Python 2.0 or better.
