As you can see the first group is the value of the fir/info/type element, the
second group title should be a combined string created out of the data of itemA
elements of a fir element.
I'd like to know if this is possible and if yes how.
This is straightforward with XSLT 2.0:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="2.0">
<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/">
<html lang="en">
<head>
<title>Test</title>
</head>
<body>
<h1>Test</h1>
<xsl:apply-templates/>
</body>
</html>
</xsl:template>
<xsl:template match="test">
<xsl:for-each-group select="fir/info" group-by="typ">
<xsl:value-of select="current-grouping-key()"/>
<br/>
<xsl:for-each-group select="current-group()"
group-by="string-join(itemA/concat(id, '-', name), ', ')">
<xsl:value-of select="current-grouping-key()"/>
<br/>
<xsl:value-of select="current-group()/concat(id, '-', num,
serie)" separator=" "/>
<br/>
</xsl:for-each-group>
<br/><br/>
</xsl:for-each-group>
</xsl:template>
</xsl:stylesheet>
With XSLT 1.0 you would need two steps I think, the first creating a
temporary result with an attribute or element having the combined value,
then you can define a key on the temporary result. If you want to
perform two steps in one stylesheet then you need to use exsl:node-set
or similar:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:exsl="http://exslt.org/common";
exclude-result-prefixes="exsl"
version="1.0">
<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:key name="k1" match="fir/info" use="typ"/>
<xsl:key name="k2" match="group/info" use="concat(../@key, '|', @key)"/>
<xsl:template match="/">
<html lang="en">
<head>
<title>Test</title>
</head>
<body>
<h1>Test</h1>
<xsl:apply-templates/>
</body>
</html>
</xsl:template>
<xsl:template match="test">
<xsl:variable name="group-rtf">
<xsl:for-each select="fir/info[generate-id() =
generate-id(key('k1', typ)[1])]">
<group key="{typ}">
<xsl:for-each select="key('k1', typ)">
<xsl:copy>
<xsl:attribute name="key">
<xsl:for-each select="itemA">
<xsl:value-of select="id"/>-<xsl:value-of
select="name"/>
<xsl:if test="position() != last()">
<xsl:text>, </xsl:text>
</xsl:if>
</xsl:for-each>
</xsl:attribute>
<xsl:copy-of select="node()"/>
</xsl:copy>
</xsl:for-each>
</group>
</xsl:for-each>
</xsl:variable>
<xsl:for-each select="exsl:node-set($group-rtf)/group">
<xsl:value-of select="@key"/>
<br/>
<xsl:for-each select="info[generate-id() = generate-id(key('k2',
concat(../@key, '|', @key))[1])]">
<xsl:value-of select="@key"/>
<br/>
<xsl:for-each select="key('k2', concat(../@key, '|', @key))">
<xsl:value-of select="concat(id, '-', num, serie)"/>
<xsl:if test="position() != last()"><xsl:text>
</xsl:text></xsl:if>
</xsl:for-each>
<br/>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
