Hi Mick,
Please find below the Muenchian Grouping solution to
the problem described by you -
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="text"/>
<xsl:key name="by-jan" match="person[birthmonth =
'January']" use="birthday"/>
<xsl:template match="/persons">
<xsl:for-each select="person[birthmonth =
'January']">
<xsl:sort select="birthday" data-type="number"/>
<xsl:if test="generate-id(.) =
generate-id(key('by-jan', birthday)[1])">
<xsl:value-of
select="birthday"/><xsl:text>
</xsl:text>
<xsl:for-each select="key('by-jan', birthday)">
<xsl:sort select="name"/>
<xsl:value-of
select="name"/><xsl:text>
</xsl:text>
</xsl:for-each>
</xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Regards,
Mukul

Thanks for the link, Michael. I was already afraid
I'd have to use Muenchian
grouping, something that I've never done before.

Subject: [xsl] sorting and grouping
I've got a sorting problem. My XML is as follows:
<person>
<name>Kermit</name>
<birthday>3</birthday>
<birthmonth>January</birthmonth>
</person>
etc.
XSLT:
<xsl:for-each
select="person[birthmonth='January']">
<xsl:sort select="birthday"
data-type="number"/>
<xsl:sort select="name"/>
<xsl:value-of select="birthday"/>
<xsl:text> - </xsl:text>
<xsl:value-of select="name"/>
<br/>
</xsl:for-each>
With the above code, each birthday number is
repeated. What I
would like is
to have the birthday number appear only once
followed by the
names of people
whose birthday that is. I suspect it can be done
by testing
if the birthday
value is the same as the preceding sibling, but I
can't get
it right. Does
anyone have any idea how to solve this?
Mick
