[Zope] conditional dtml-in ?

[Thomas B. Passin]

I suggest that you use one dtml-in loop to build up a list that contains
only the elements that you want, then do a dtml-in loop on that array.

Cheers,

If I do

<dtml-if expr="my_attribute == 1">
   <dtml-in>
   </dtml-in>
</dtml-if>

my_attribute isn't an attribute of each sequence_item

If I do

<dtml-in>
   <dtml-if>
   </dtml-if>
</dtml-in>

I cannot use the dtml-in modifiers, like start="1", size="10">...
I mean, I can use them but I'd like them to mean "start from position 1 of
the sequence of the items matching the where-like clause" and "take the
first 10 elements of the sequence of the items matching the where-like
clause". Am I wrong?
