[Zope] Complex dtml-in/ZopeFind ?

[Tino Wildenhain]

Hi Kai,

thats simple. You have too much logic in your dtml.
First of all I would do it rather with a zcatalog search,
since this would not call all documents (e.g. load them
into memory) and gives you the flexibility on choosing
whatever subset you want.

If not, you should put all your search stuff into a
python script, which returns a list of
only the objects you want.

If you use query-start/end you could as well put the
<table> </table> stuff there as well.

If you dont, you can drop these lines and put
them all outside, so there is no need to see how
many items are returned.
