[Zope] while

[Patrick Lewis]

This is real ugly, but you asked (untested, but you get the idea):

<dtml-try>
  <dtml-in "_.range(1000)">
    <dtml-if whileCondition>  <!-- Your logic test -->
      <!-- Do stuff in while loop -->
    <dtml-else>
      <dtml-raise type="conditionFalse">errormsg</dtml-raise>
    </dtml-if>
  </dtml-in>
<dtml-except conditionFalse>
  <!-- Fall out of 'while' loop.  -->
<dtml-else>
  <dtml-raise type="RangeError">Oops! Exception never raised.</dtml-raise>
</dtml-try>

This only works if the loop will cycle less than 1000 times.  Needless to
say, this is done a lot easier in Python.
