You should use a recursive mathod.

Write one method recursiveMethod:

def recursiveMethod(obj):
     result = []
     if obj.parent != None:
          result = recursiveMethod(obj)
     if obj.meta_type=='KBItem':
          result.append(obj.Title)
     return result

Then call this method like:

def GetParentNames(self):
     recursiveMethod(self)


This code is untested, but should work.

Stephan
