[Zope] nested dtml-with

[Paul Zwarts]

Ah, lol.. No. Sorry... I must not be making much sense.

I wont explain everything because it would really sound strange. Long
story short, I have a list which is basically the location of a document
(folder, folder2, index_html = folder1.folder.index_html).

>From a method called from the root of the site: /index_html

I want to basically do the same as this code:

<dtml-with folder 1>
  <dtml-var index_html>
  <dtml-with folder2>
     <dtml-var index_html>
  </dtml-with>
</dtml-with>

But instead using the list. The reason is that every folder may or may
not have an index_html, and any directory that DOES have one in the
traversal path from root to the end of the list (folder1 to
folder2.index_html (3 steps)) will be rendered into the document. 

So I would get something like:

<!-- this is from /folder1/index_html !--/>
<h1>Folder 1</h1>

<!-- this is from /folder1/folder2/index_html !--/>
<h1>Folder2</h1>

The trick is that I am currently in the root namespace. I tried
ascending the tree with the code I pasted earlier, but it seems to just
query all iterations from root, and of course this doesn't work.  

Did I explain any clearer or worse?

Thanks,
Paz

You need to define a Python script called subTree ... see my code
example.

You are either talking nonsense, skipping several lines of thought, or I

havn't understood a bit! Was your problem not that you wanted to get a 
list of all objects and subobjects in a folderish object?
