I have a reindex method that does this: (simplified)

<dtml-in "objectItems(['my zclass types - could be Folders for you')">
Indexing &dtml-id; ...
  <dtml-with sequence-item>
    <dtml-call "this().reindex_object()">     <<<< Whatever you want done
on each item
 ... Done: <dtml-var "this().absolute_url()"></br>
  </dtml-with>
</dtml-in>

<dtml-in "objectItems(['Folder'])">
  <dtml-with sequence-item>
<b>Entering <dtml-var id></b></br>
    <dtml-var reindex>                        <<<< The recursive call!
  </dtml-with>
</dtml-in>
