[xsl] Eliminating duplicates while processing

[José Carlos Ramalho <jcr@xxxxxxxxxxxx>]

Hi all, I am having the following problem:

I want to process a list of nodes that can appear at several different
points of the structure, and I ant to process them in a particular order.
This is easy to specify:

        for-each select="//node-name"
            sort select="criteria"

The problem is that I want to supress the node's processing if it is equal
to the one that precedes it in that order. How can I have access to the last
processed node while processing the current one?

TIA
