People suggesting DTML still has a place in Zope.
You shouldn't need to learn two templating languages and a scripting language 
just to use one web framework ;-)

No, and neither is DTML. But DTML makes it easier for you to think you can put 
application logic into it without being horribly burned later.

You should _never_ _ever_ have content and logic in a single method!

Jeez, this is documented and painfully simple:

<tal:i repeat="item here/objectItems">
<tal:x replace="item"/>
</tal:i>

Of course, you probably want to display that, so something like the following is 
more likely:

<table>
<tr tal:repeat="item here/objectItems">
<td tal:content="item">Sample content</td>
</tr>
</table>

In a python script, it'd be:

for item in context.objectItems():
    print item() # this line might need ot be edited
                 # depending on what the items are
return printed

Now, any other excuses why you think DTML should still exist? ;-)

cheers,
