[Zope] DTML-In with filter

[Andrew Milton]

+-------[ Martin Koekenberg ]----------------------
| Hello,
|  
| Is it possible to use a DTML-In to display all DTML Documents in a folder exept
| the one's with a centain value in a property ?
|  
| Example.
|  
| DTML Document one with property a=bc
| DTML Document two with property a=de
| DTML Document three with property a=bc
|  
| Now I want to use DTML-IN to display all the dtml documents except the ones
| with property a=de.
| I also use the size and batchsize property to create links to the next 10
| documents..... If I use an if statement the next 10 can be 9 ore less 9 items
| because there could be one ore more documents with a=de.
|  
| Who can help me ?

Pseudo-code (dtml-like)

<dtml-in "someListOfThings">
    <dtml-with thecurrentitem>
        <dtml-unless "a=='de'">
            <dtml-var thecurrentitem>
        </dtml-unless>
    </dtml-with>
</dtml-in>

Or you could write a python script that filtered out the ones you wanted and
call the python script to return the list of things to display, which is
probably a much better idea.
