[Zope] Recursively show content of document in subfolders

Dear all, example I have a directory structure like this: zoo -- |-- birds | |-- mamals |-- reptiles Each subfolder (birds, mamals, reptiles) has a DTML Method called 'description' which contains a short description of each group of animal. I want to make a DTML Method in zoo folder that show the description of each group of animal. How to do it in Zope? Thanks. -- mico@cbn.net.id --- Ph. 62-22-2505549 ICQ #12521756
