Re: how to update a variable (grouping question)

Please try this XSL..

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">

<xsl:output method="xml" indent="yes" />

<xsl:template match="/schedule">
   <schedule>
     <xsl:apply-templates select="row" />
   </schedule>
</xsl:template>

<xsl:template match="row">
   <xsl:choose>
     <xsl:when test="col[2] = 'Opponent'">
       <xsl:call-template name="groupSiblings">
         <xsl:with-param name="month" select="col[1]" />
         <xsl:with-param name="list" select="following-sibling::row" />
       </xsl:call-template>
     </xsl:when>
     <xsl:otherwise />
  </xsl:choose>
</xsl:template>

<xsl:template name="groupSiblings">
   <xsl:param name="month" />
   <xsl:param name="list" />

   <xsl:if test="not($list[1]/col[2] = 'Opponent')">
     <date><xsl:value-of select="$month" /><xsl:text>
</xsl:text><xsl:value-of select="$list[1]/col[1]" /></date>
     <xsl:if test="count($list) &gt;= 2">
       <xsl:call-template name="groupSiblings">
         <xsl:with-param name="month" select="$month" />
         <xsl:with-param name="list" select="$list[position() > 1]" />
       </xsl:call-template>
     </xsl:if>
   </xsl:if>
</xsl:template>

</xsl:stylesheet>
