[Zope] dtml-in sorting on lists

[ririe@spininternet.com]

Hi,

   I would like to use dtml-in's sort functionality, but on indices
of lists, not attributes.

    Basically, I have a function, say getLoL() that generates a list of 
lists ( e.g. [ [A1,A2,A3],[B1,B2,B3], ...]
  
    I can use dtml-in to loop through this like:

<dtml-in expr="getLoL()">
First index: <dtml-var expr="_.getitem('sequence-item')[0]"> 
</dtml-in>

How can I now sort based on say the second index of the sequence-item?
(ie sort A2, B2, C2, etc)

I've looked at the DT_In.py code, and think I need to make
modifications to allow for indexing (as opposed to getattr's)
but was wondering if there was an existing way.

Thanks,
Robert
