[Zope] checking sequence-item variable?

[Phil Harris]

Ethan,

Try something like (tested, but not in this situation, i.e. I use it a lot
and it works YMMV):

<dtml-with "PARENTS[-1].net" only>
  <dtml-in "objectValues(['Folder'])">
    <dtml-in aq_explicit only>
      <dtml-unless noshow>
        do something
      </dtml-unless>
    </dtml-in>
  </dtml-in>
</dtml-with>

HTH
