[Zope] Exiting a Loop

[David H]

Asad,
You want to break out of a DTML loop but there is no loop breaking DTML 
syntax. 

Here is another candidate DTML work-around:

<dtml-in someSequence>
  <dtml-if someCondition> 
      whatever you do in the loop
  </dtml-if>
</dtml-in>

That way, you can avoid processing past a certain point, just that the 
loop will run until the sequence reached the end.  Of course if your 
sequence is huge then this would be costly in terms of processing time 
and then you should play the python card.
