[Zope] Displaying the Contents of a Local File System Object

Hello. Does anyone know how to iterate over the contents of a 'Local File System' object? I have two 'File' objects that lie within the 'Local File System' object. I cannot use the objectValues method with the dtml-in or tal:repeat tags since this method is only defined for folders not for 'Local File System' objects. Your help would be greatly appreciated. Thanks. - Asad
