[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Re: xsl:sort and xsl:count issues (solution, long mes
 Hi, Rolando,
You actually have a multi-level grouping problem. I have used a variant of
Ken Holman's multi-variable approach (mentioned a couple times in the last
few weeks on this list if you need more examples) to create a solution.
When I apply this XSL file:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<table>
<!-- Put all the distinct type values into a variable -->
<xsl:variable name="types"
select="//type[not(following::type=.)]"/>
<xsl:for-each select="$types">
<tr>
<td colspan="4">Type: <xsl:value-of select="."/></td>
</tr>
<!-- For each type, create a list of distinct creators who made
a work of that type -->
<xsl:variable name="currentType" select="."/>
<xsl:variable name="creators"
select="//oai_dc[type=$currentType]/creator[not(following::oai_dc[type=$curr
entType]/creator=.)]"/>
<!-- Now that we have our trusty gang of creators, make listings
per creator -->
<xsl:for-each select="$creators">
<xsl:sort/>
<xsl:variable name="currentCreator" select="."/>
<xsl:for-each
select="//record[metadata/oai_dc/type=$currentType][metadata/oai_dc/creator=
$currentCreator]">
<tr>
<td><xsl:value-of select="$currentCreator"/></td>
<td><xsl:value-of select="metadata/oai_dc/title"/></td>
<td><xsl:value-of select="metadata/oai_dc/date"/></td>
<td><xsl:value-of
select="metadata/oai_dc/publisher"/></td>
</tr>
</xsl:for-each>
</xsl:for-each>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

for brevity's sake):
