Sorry, I should have added : recursively !!!

No, what I want is the following list (with your example):

['FolderA1', 'FolderA2A', 'FolderB', 'FolderC']

Yes I'm sorry:

From a Folder, I want to recursively search for all "terminal" folders
(leaves) and build a list of these folders.

bye "terminal" folder, I mean a folder with no subfolder.

The following should give me exactly the result I want, if only I knew how
to write it in a way accepted by the dtml parser: 

<dtml-let myresult="ZopeFind(this(), obj_metatypes=['Folder'],
search_sub=1, obj_expr=""" not objectValues(['Folder']) """ )">
  ...
</dtml-let>

My actual solution is to do :

<dtml-let myresult="ZopeFind(this(), obj_metatypes=['Folder'],
search_sub=1)">
  <dtml-if "not objectValues(['Folder'])">
    ...
  </dtml-if>
</dtml-let>

but this solution is not good because if I need len(myresult) it returns
me the total number of folders, not the number of "terminal" folders, and
I find it stupid to have to build a new list in a <dtml-in> and then
loop over the new list in a second <dtml-in> because I know ZopeFind is
the solution: can do it, I've tested it with the Find tab.

My only problem is: What is that f... syntax ? 

Any DTML Syntax guru out there ?

thanks in advance.
