[Zope] How to change view of all *.txt?

Hi, Is there a way to assign a handler to some objects based on type or name, similar to what Apache allows? For example, I want to have all *.txt files be processed by a certain external method. Is there any way to do this? Currently, I'm doing it by generating links to my .txt objects that are actually calls directly to my method with the object name as a paramter... It works, but it's a hack. Thanks, Robb
