First, I apologize in advance: this is more a minor syntax problem than 
anything else,
and a combination of my laziness and incompetence at basic programming 
("I'm a SysAdmin,
not a **programmer**!!")

I have modified Tres Seaver's STX_Document product to include a property 
"topic".
I have figured out how (stolen the code) to sort all the 'STX_Document's 
within a folder,
sorting all documents by property and arranging them in a table.

    <dtml-in 
expr="_.sequence.sort(PARENTS[0].objectValues(['STX_Document']),
                                      (('topic', 'nocase'),
                     ('title','cmp'),
                                      ))">

         <th><dtml-var topic></th> <td><a href="<dtml-var 
URL1>/<dtml-var id>">
                               <dtml-var title>                 
&quot;<dtml-var description>&quot;

What I'd like to do next is grab each property in a variable to compare 
against the value
of the **next** iteration. If it matches, don't print the topic name in 
the table header. If it doesn't match, print the topic name and set the 
temp variable to the new value.

I **realize** this a basic department sort/subtotal algorithm, but I 
don't have the familiarity
with Zope syntax to work it out, and deadlines lay poised like a gun 
pressed against my temple.

Any tips, clues, helpful hints or seeing-eye dog coupons will be 
gratefully appreciated....

peace
