Yes, what I did was to look at the RFC that you sent me then look at the 
WebDAV properties that DAVExplorer reads.  The properties for the source 
list looks like...

<n:source>
  <n:link>
     <n:src>
         /test_dtml
     </n:src>
    <n:dst>
        /test_dtml/document_src
    </n:dst>
  <n:link>
</n:source>

... the property tagged by dst is the link to the unrendered source. 
What I really need to do is extract this from the properties rather than 
simply appending /document_src onto the end of everything. As you point 
out (partially) document_src has no meaning in the context of some 
objects and also other WebDAV servers may use a different syntax than 
simply adding /document_src on the end of the URL.

At least this works for Zope. For my next trick ;^) I am going to try to 
make it general, as you suggest and add a "Get Source" menu option so 
that the user has some choice over getting the rendered or unrendered 
source. Also, I am working on adding an "Edit" option which does a "get 
source" into a temp file then fires up the user's editor of choice and a 
thread to monitor the modification time of the temp file. Each time the 
file changes it gets put back into Zope. That way the user can use the 
"Save" command on the editor. (By the way I E-mailed the authors of 
DAVExplorer to get their input. waiting for a reply.)

   Anyway I'm having fun and getting somewhere at last!!
