[Zope] something like getpath in ZCatalog for methods

Hi there, is it possible to get the absolut position/url of a method (e.g. method_X) that is located somewhere in one of the above parents folders? Something like getpath in ZCatalog. Looks like this: Folder_A testing_method method_X Folder_A1 Folder_A1.2 method_X Folder_A1.3 Folder_A2 Foder_B Folder_B1 method_X Folder_C ... Calling "testing_method" in "Folder_A1.2" should give a the the position of "method_X" in "Folder_A1.2" Calling testing_method in "Folder_B.1" should give a the the position of the "method_X" in "Folder_B1" In other words: whats the position of my next "method_X" Thanks a lot Marcus
