Re: [xsl] alternate backgrounds problem...

[Josh Canfield <joshcanfield@xxxxxxxxx>]

You can use position() and mod on a per portlet basis because you are
calling apply-templates with a union of all the section and link
nodes.

If you named your styles using the convention back-white-0 and back-white-1

   <xsl:template match="link">
       <xsl:variable name="colour" select="../@colour"/>
       <xsl:variable name="desclength" select="string-length(../description)"/>
       <div class="back-{$colour}-{position() mod 2}">
           LINK CONTENT
       </div>
   </xsl:template>
