[Zope] Looping in DTML

[Phil Harris]

As for breaking out of a loop, how about (extremely untested):

<dtml-try>
 <dtml-in "_.range(total_count)">
   <dtml-var sequence-item>
   <dtml-if some_thing>
     <dtml-raise someexception></dtml-raise>
   </dtml-if>
 </dtml-in>
<dtml-except someexception>
  <dtml-comment>
    do nothing
  </dtml-comment>
</dtml-try>

the raise tag should then jump to the except tag and therefore out of the
loop or something like that, maybe, possibly, ;).
