[Zope] single iterations over duplicate values

[Kevin Carlson]

Take a look at <dtml-var first-xxx>.  For example, if you the duplicate 
value you want to check for is named "test", you can check to see if the 
current iteration is the first iteration by using something like:  
<dtml-if first-test>.

I think you need to sort the result set by the column you want to check.
