But that assumes that they are all in the same folder... a ZCatalog query where meta-type = 'DTML Document' followed by a simple sequence-length would get around that. And I think (but dont quote me on this) that a ZCatalog search is quicker than objectValues. ----- Original Message ----- From: "Erik Enge" <erik@src.no> To: "Alexander Limi" <alexander@limi.net> Cc: <zope@zope.org> Sent: Tuesday, June 27, 2000 1:35 PM Subject: Re: [Zope] ZCatalog counting?

Is there an easy way to count the number of occurences of a certain meta type in a Catalog? E.g: I want a dtml snippet that outputs:
Couldn't you do:
<dtml-call "REQUEST.set('counter', 0)">
<dtml-in "objectValues('DTML Document')"> <dtml-call "REQUEST.set('counter', counter+1)"> </dtml-in>
This folder (<dtml-var title_or_id) has <dtml-var counter> number of objects with the meta type DTML Document.
