Hi want to call ZopeFind to find all folders in the current folder which doesn't have got any subfolder. the following query works but returns all folders, even those which have got subfolders: <dtml-let myresult="ZopeFind(this(), obj_metatypes=['Folder'], search_sub=1)"> <dtml-in myresult> ... </dtml-in> So I play a little with the Zope Search Interface and I find that if I type in "not objectValues(['Folder']" (without the double quotes) in the obj_expr (Expression) field then this solves my problem. my question is: How to rewrite my ZopeFind with obj_expr="not objectValues(['Folder'])" ? I've tried with or without quotes (single, double and even triple ones), but with no luck: I've always got a Document Template Parse Error. What is the correct syntax please ? Actually I've added a test inside my dtml-in loop but I think it's stupid because I need the exact result length and I don't want to rebuild a list of matching results since the Zope Search Interface can do it. thanks in advance for any answer.

Couldn't you just do a nested dtml-in? It's kind of hacky, but... <dtml-in "objectValues(['Folder']"> <dtml-in "objectValues(['Folder']"> <dtml-else> <p><dtml-var title_or_id> has no folders. </dtml-in> </dtml-in> you may or may not have to change the dtml-var statement to get the correct title-or-id.

No this can't help because I don't know how deep is my hierarchy: I've delegated folder creations to at least ten persons. I'm sure I can do it with ZopeFind, because Zope do it in the Find (Advanced) tab, but don't know the exact syntax of: """ obj_expr = "not objectValues(['Folder'])" """ (which doesn't work because of nested " and ') Actually I've put a <dtml-if> inside of my <dtml-in> loop, but it limits my possibilities, especially because my result length is overestimated (all folders vs only folders with no subfolders). thanks anyway for your answer. bye, Jerome ALET - alet@unice.fr - http://cortex.unice.fr/~jerome Faculte de Medecine de Nice - http://noe.unice.fr - Tel: 04 93 37 76 30 28 Avenue de Valombrose - 06107 NICE Cedex 2 - FRANCE

I'm confused. You said you only were concerned about the _current_ directory's subdirectories not having sub-directories, right? IOW You have: ROOT FolderA -FolderA1 -FolderA2 /FolderA2A FolderB FolderC And in ROOT, you only want to see : FolderB FolderC And in FolderA: FolderA1 Right? If so, whether or not FolderA1 has subfolders is irrelevent in root. The code ethan posted will provide you with that. I have very similiar code for one of my nav-systems, opnly it is the opposite, I show folders (and various other objects) and their subfolders (and various other objects) only.
I'm sure I can do it with ZopeFind, because Zope do it in the Find (Advanced) tab, but don't know the exact syntax of:
""" obj_expr = "not objectValues(['Folder'])" """
(which doesn't work because of nested " and ')
Actually I've put a <dtml-if> inside of my <dtml-in> loop, but it limits my possibilities, especially because my result length is overestimated (all folders vs only folders with no subfolders).
Maybe I read it wrong, but I thought you said you wanted only folders with subfolders _in the current directory_. Maybe you need to rephrase your question? Bill -- "Linux: the operating system with a CLUE... Command Line User Environment". seen in a posting on comp.software.testing

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.

Personally, something like this I would do in python. IMO, deep recursion belongs in python,not DTML. -- Do not meddle in the affairs of sysadmins, for they are easy to annoy, and have the root password.
