[Zope] re: Length of results set

[Dylan Reinhardt]

Oh, sorry... I think I figured out what you're after...

Try:

<dtml-call "REQUEST.set('my_langs', [])">
<dtml-let langShort="lang[2:]">
   <dtml-in objectValues>
     <dtml-if "id==langShort">
       <dtml-call "my_langs.append(langShort)">
     </dtml-if>
   </dtml-in>
</dtml-let>

You found <dtml-var "_.len(my_langs)"> matches: <UL>
<dtml-in my_langs>
   <LI><dtml-var sequence-item></LI>
</dtml-in>
</UL>

Does *that* do it?

Sorry about the last post...

Dylan
