Hello,
I have a couple of xml-documents, all with the same structure:
<?xml version="1.0" encoding="UTF-8"?>
<responses>
<response for="js0" correct="correct">C</response>
<response for="js1">A</response>
<response for="js2" correct="correct">A</answer>
<response for="db0" correct="correct">A</response>
<response for="db1">B</response>
...
</responses>
I use an xml-file to collect all this documents:
<?xml version="1.0" encoding="UTF-8"?>
<alldocs>
<a href="184855.xml" />
<a href="190026.xml" />
...
</alldocs>
I woul like to group all <response> by @for over all documents and then
count how many from them has an @correct.
My solution is the following (which works for me):
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="html" indent="yes" encoding="iso-8859-1" />
<xsl:template match="/alldocs">
<xsl:variable name="alldocs">
<xsl:for-each select="document(a/@href)">
<xsl:copy-of select="/responses/response" />
</xsl:for-each>
</xsl:variable>
<html>
<head><title>Responses</title></head>
<body>
<xsl:for-each-group select="$alldocs/response" group-by="@for">
<p>
<b><xsl:value-of select="current-grouping-key()" />=</b>
<xsl:for-each-group select="current-group()"
group-by="@correct">
<xsl:value-of select="count(current-group())" />
</xsl:for-each-group>
</p>
</xsl:for-each-group>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
Is there a better solution?
(for exmaple if I would like to sort the output by the number of
@corrects)
Regards
Thomas
