Subject: Re: [xsl] Displaying Unique attribute value From: Syd Bauman <Syd_Bauman@xxxxxxxxx> Date: Wed, 29 Oct 2008 10:12:15 -0400 |
I think maybe I don't understand the desired input & output quite correctly here. I would have thought something like <xsl:if test=" normalize-space( @page-num ) != normalize-space( preceding::*[@page-num][1]/@page-num )"> would do the trick. Is there something wrong with this approach that I'm missing? Perhaps the grouping approach suggested is significantly more efficient? > > Each and every element is having page-num attribute.
