[xsl] grouping-problem

2007-06-14 02:02:37
Hi,
I'm working with
XSLT 2
Saxon 8
And I am a newbie with XSLT...

----
Here is the XML file 
"stats.xml"

<statistic>
<class name="CI_Citation" associationName="citation" count="50">
</class>
<class name="CI_Citation" associationName="title" count="100">
</class>
<class name="MD_Metadata" count="300">
</class>
<class name="MD_Metadata" associationName="parentId" count="3">
</class>
<class name="CI_Citation" associationName="citation" count="60">
</class>
<class name="CI_Citation" associationName="title" count="200">
</class>
<class name="MD_Metadata" count="50">
</class>
<class name="MD_Metadata" associationName="parentId" count="10">
</class>
[...]
</statistic>
----

Output should be a csv-textfile like:

CI_Citation             citation        110
                        title           300
MD_Metadata                             350
                        parentId        13
----

I managed quite well, but only did my XSLT not consider the class
MD_Metadata without the "associationName":

"stats.xsl"

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
        <xsl:output encoding="ISO-8859-1"/>
        <xsl:output method="text"/>
<xsl:template match="/">
                <xsl:apply-templates select="statistic"/>
</xsl:template>
[...]
<xsl:for-each-group select="class" group-by="@name">    
  <xsl:value-of select="current-grouping-key()"/>
                <xsl:for-each-group select="current-group()"
group-by="@associationName" >
                        <xsl:text>;</xsl:text>
                        <xsl:value-of select="current-grouping-key()"/>
                        <xsl:text>;</xsl:text>
                        <xsl:value-of select="sum(current-group()/@count)"/>
            </xsl:for-each-group>
</xsl:for-each-group>
[...]
----

Is there a possibility to list the class MD_Metadata even if there is no
"associationName"? Thanks for your reply!
