Just drop this DTML... or at least get help from python:

return [doc for doc in context.objectValues('DTML Document')  if 
doc.getProperty('a')!='de']

(python script or the like would be your friend - also
it makes it possible to replace the quite costy objectValues()
call with ZCatalog query w/o changing your presentation code)
