Recap: There are several section elements containing a variable number of child
elements. I want to return a count of all the child elements and identify the
mid point of all the child elements. I then want to split the parent section
elements after the parent containing the middle child.
I have this working on my local machine using MSXML, but it fails when I
convert it on the staging servers using Xalan Java 2.4.1 and I'm stumped.
Relevant XSL:
<xsl:variable name="gearMid"
select="generate-id((//rec_gear_sec/*)[round(count(//rec_gear_sec/*) div 2)])"/>
<xsl:template name="rec_gear_list">
<xsl:for-each select="//rec_gear_sec/*">
<xsl:if test="generate-id(.) = $gearMid">
<xsl:variable name="splitPoint"
select="count(../preceding-sibling::*) +1"/>
<div style="width:275; float:left;padding-right:10px;">
<xsl:apply-templates select="//*[position()
< $splitPoint and name()='rec_gear_sec']"/>
<xsl:apply-templates select="parent::*"/>
</div>
<div style="width:285; float:right;">
<xsl:apply-templates select="//*[position()
> $splitPoint and name()='rec_gear_sec']"/>
</div>
</xsl:if>
</xsl:for-each>
</xsl:template>
That for-each is probably a little inefficient, but the real problem is the
output. In Xalan it gets the group in the first div right, but in the second
div it gives me *all* the rec_gear_sec elements, not just the ones with a
position() greater than $splitPoint. It seems like this is a bug, and I could
really use a workaround. I've already spent far more time on this one than it
deserves. Any ideas?
