Hey Hardy,
Why not use the same math logic against the district_id?
Such like:
<xsl:if test="district_id mod 2 = 0">
...do this?
</xs:if>
The following code might make your recursive problem a bit easier to
manage as well using apply-templates instead of for-each to put the
code into seperate templates that can easily be managed and modified
"outside" of the code-base it will subsequently become back together
with in the output:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
<xsl:template match="/">
<xsl:apply-templates select="legislators"/>
</xsl:template>
<xsl:template match="legislators">
<table>
<xsl:apply-templates select="legislator"/>
</table>
</xsl:template>
<xsl:template match="legislator">
<xsl:variable name="did">
<xsl:choose>
<xsl:when test="district_id mod 2 = 0">
<xsl:text>#fff</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text>#ccc</xsl:text>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<tr style="background:{$did}">
<td>
<xsl:value-of select="name"/>
</td>
</tr>
</xsl:template>
</xsl:stylesheet>
Hope this helps!
Cheers!

The typical way of alternating the background color of every other row
in an HTML table is something like this:
<xsl:for-each select="msxsl:node-set($sorted_legislators)">

<xsl:if test="position() mod 2 = 0">
<xsl:attribute
name="bgcolor">#eeeeee</xsl:attribute>
</xsl:if>
------------------------------------
My situation is this - the for-each is based on legislators sorted by
district - here's a sample (not real) xml to illustrate:
<legislators>
<legislator>
<name>Joe</name>
<district_id>1</district_id>
</legislator>
<legislator>
<name>Bob</name>
<district_id>2</district_id>
</legislator>
<legislator>
<name>Pete</name>
<district_id>2</district_id>
</legislator>
</legislators>
There will be one *or more* legislators for each district. Instead of
alternating the background color for every *legislator*, I want to
alternate the background color for every *district*. In other words, I
want Joe in district_id 1 to have white background, but I want both Bob
and Pete in district_id 2 to have a gray background. But since I can't
change the value of a variable (can't increment a counter), I don't know
what I can base the bgcolor alternation on.
The xsl:for-each is based on a select of a variable containing all
legislators sorted by district.
I know there is probably an easy way to do this, but I don't know it.
Help!
Thanks.
Hardy Merrill
