[Zope] zcatalog: truncating getpath(data_record_id_)?

Hi I have my Zope return a list of URLS from a ZCatalog in this out-of-the-box way: <a href="<dtml-var "Catalog.getpath(data_record_id_)">"><dtml-var id></a> The objects in this particular Catalog are all subclassed objects of a certain zclass. When users click on the above links, they see metadata results. I want to change this. Instead, I want users to see the default view of the subclassed object's container. Should I be trying to figure out how to truncate the results of getpath(data_record_id_)? How do I do this? Any help would be greatly appreciated. Cheers, Anthony
