RE:  More XPath 1.0 Expression help
Take a look at http://www.jenitennison.com/xslt/grouping

Most of the techniques for grouping are at the XSLT level, but you can use
the basic

key[not(. = preceding-sibling::key)]

if you don't mind O(n^2) complexity.

This detects the distinct values: leave out the not() and you have an
expression that detects the duplicates.
