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>

i am creating portlets for a webpage, each portlet has any number of
"section" divs and "link" divs in any order. I am trying to create alternate
background colours on these divs by using the xsl. For example, for a white
portlet, i would want:
link div - no background (white)
section div - grey background
section div - no background
link div - grey background
etc.......
I think i may have to do something with parameter passing but not sure how
to tackle it. I thought about maybe counting the number of divs in each
portlet and then saying for every even numbered div have no background and
every odd numbered div have a coloured background. However, i dont think you
can figure out which divs would be odd and which would be even? My xml and
xsl is below:
I have an xml file like this:
<page>
<portlet colour="white">
<link>
<name></name>
</link>
<link>
<name></name>
</link>
<section>
<name></name>
</section>
.......any number of mixed sections and links
</portlets>
<portlet colour="blue">
<link>
<name></name>
</link>
<link>
<name></name>
</link>
<section>
<name></name>
</section>
.......any number of mixed sections and links
</portlets>
</page>
part of my xsl file looks a bit like this:
<xsl:template match="portlet">
<xsl:variable name="colour" select="@colour" />
<div class="portlet-content" id="ne-portlet-content">
<!-- place description in portlet -->
<xsl:if test="string-length(description) != 0">
<div class="back-none">
<p><xsl:apply-templates select="description" /></p>
</div>
</xsl:if>
<!-- place links/sections in portlet -->
<xsl:apply-templates select="link | section"/> <!-- linkc |
section-->
</div>
</xsl:template>
<xsl:template match="link">
<xsl:variable name="colour" select="../@colour"/>
<xsl:variable name="desclength"
select="string-length(../description)"/>
<div class="back-{$colour}">
LINK CONTENT
</div>
</xsl:template>
<xsl:template match="section">
<xsl:variable name="colour" select="../@colour"/>
<xsl:variable name="desclength"
select="string-length(../description)"/>
<div class="back-{$colour}">
SECTION CONTENT
</div>
</xsl:template>
