Re: distinct-values work-around for Xpath 1.0

From: Richard Braman <rbraman@------------.--->
To: NULL
Date: 4/10/2010 3:33:00 PM
<?xml version="1.0" encoding="UTF-8"?>
<!--I am having a similar problem although my xml is a little more

Height, etc only show up once.  This uses XSLT 1.0, so distinct-values()
is not an option :(:-->
