[Zope] conditional dtml-in ?

[Meilicke, Scott]

Can you build a list based on your conditional, then cycle through that
list?

<dtml-in>
   <dtml-if expr=3D"my_attribute =3D=3D 1">
	<code to make a new list>
   </dtml-if>
</dtml-in>

<dtml-in new list>
</dtml-in>

Does anyone have a code snippet to share to make a new list?

If I do

<dtml-if expr=3D"my_attribute =3D=3D 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=3D"1", size=3D"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?
