Creating and adding Nodes in the XMLDocuments

14 Jan 2000

      Hello Everyone,

Does someone knows XMLDocuments and DOM pretty well. Well then I have a
nut for you to crack:

Short Form:
I am implementing a little message board using XML documents. How can I
create Nodes, so I can add them to the document or are there other ways
to do it?

The Long Form:
For projects I do as living I alway keep all documentation in HTML and
XML. I also have a task list, with dates and status in XML form. Now I
thought it would be a good idea, if co-workers and clients could comment

on some of the task descriptions or write some updates about the tasks.
I thought that it would be great if this could be in the form of a small

Message Board saving all the comments in the same XML file for
completeness.

My XML will look something like this:
(There is actually more XML, but it is irrelevant to this case.)
...
<task ... >
   <start>...</start>
   <end>...</end>
   <abstract>...</abstract>
   <messages>
       <message name="Subject">
           <date>...</date>
           <author>...</author>
           <body>...</body>
           <replies>
                <message>....</message>
           </replies>
      </message>
      ...
   </messages>
</task>

With the help of Zope, how can I add a single message into either the
'messages' or the 'replies' not using the Zope management interface and
only a programmable way.
Well I thought using acquisition I prepare the addMessage method in the
root folder of the XML document. Therefore I can reach it from every XML
node. I also do not have to worry then about passing  the URL. Now I
have already the parent node for my message, making use of
absolute_url() and objectValues(). And I know there is a XML function
let me add another node.
MY PROBLEM: I do not know how to create a node or to add one simply to
the document. Is that really that hard?

Thank you guys for your great help and work.

Regards,
Stephan
