[Zope] (Newbie) Tree based sitemap using Zope book example

[Adrian Blockley]

Hi All,

I am trying to develop a website that has a tree based site map on each
page. I have used an example in the Zope book where an objects appearence
in the sitemap depends on setting a property SiteMap and uses a small
Python script to test whether the property has been set.
 
The calling dtml method uses the following code:-

<dtml-tree branches="PublicObjects" skip_unauthorized="1">
  <a href="&dtml-absolute_url;"><dtml-var title_or_id></a>
</dtml-tree>


which in turn calls the following script.

""" 
Returns sub folders and DTML documents that have 
a true 'siteMap' property. 
""" 
results=[] 
for object in context.objectValues(['Folder', 'DTML Document']):
     if object.hasProperty('siteMap') and object.siteMap:
         results.append(object) 
return results


This works fine in that context.objectValues(['Folder', 'DTML Document'])
displays a tree based site map but of course creates it relative to the
current folder object.  For the life of me I can't work out how to change
the script or the call so that the tree that is displayed is always the
root tree or rooted in any specified arbitary folder. Is it possible to
specify a context rather than the current one? - I presume it is I just
don't understand Zope (or Python...) enough to work out how to do it...

Zope is a fantastic product but my head is still spinning from the learning
curve...

All help appreciated.

Cheers Adrian
