I am unable to provide two values in group-by attribute. Please
suggest how to achieve this.

binding a variable in outer loop is giving the group position with
respect to outer loop. But I need the position with respect to inner
loop.
I think you need to reorganize your grouping code to achieve the output you
want. Try whether the following does what you want:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="2.0">
<xsl:output indent="yes"/>
<xsl:template match="articles">
<sections>
<section-title>Contents</section-title>
<xsl:for-each-group select="row" group-by="tokenize(col[2], '\|')[1]">
<xsl:choose>
<xsl:when test="contains(col[2], '|')">
<xsl:variable name="outer-key" select="current-grouping-key()"/>
<xsl:for-each-group select="current-group()"
group-by="tokenize(col[2], '\|')[2]">
<section>
<xsl:if test="position() eq 1">
<section-head><xsl:value-of
select="$outer-key"/></section-head>
</xsl:if>
<section-subhead><xsl:value-of
select="current-grouping-key()"/></section-subhead>
<xsl:apply-templates select="current-group()"/>
</section>
</xsl:for-each-group>
</xsl:when>
<xsl:otherwise>
<section>
<section-head><xsl:value-of
select="current-grouping-key()"/></section-head>
<xsl:apply-templates select="current-group()"/>
</section>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</sections>
</xsl:template>
<xsl:template match="row">
<para>
<page><xsl:value-of select="col[3]"/></page>
</para>
</xsl:template>
</xsl:stylesheet>
In your original stylesheet you end up with three groups in the outer
grouping and then the inner grouping simply has only one group for each of
the (last two) groups in the outer grouping.
