Hi Leonid,
Below is a XSLT 2.0 solution for this:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="2.0">
<xsl:output method="xml" indent="yes" />
<xsl:template match="/">
<Totals>
<xsl:for-each select="All_Results/Result[1]/*">
<xsl:variable name="name" select="name()" />
<xsl:element name="{$name}">
<xsl:for-each-group select="../../Result/*[name() = $name]"
group-by=".">
<xsl:if test="not(normalize-space(.) = '')">
<Tag value="{.}" count="{count(current-group())}" />
</xsl:if>
</xsl:for-each-group>
</xsl:element>
</xsl:for-each>
</Totals>
</xsl:template>
</xsl:stylesheet>
When the above stylesheet is applied to XML:
<All_Results>
<Result>
<Name>John</Name>
<Country>UK</Country>
<!-- other upto 100 elements -->
<Color>Red</Color>
</Result>
<Result>
<Name>John</Name>
<Country>US</Country>
<!-- other upto 100 elements -->
<Color>Green</Color>
</Result>
<Result>
<Name>Thomas</Name>
<Country>Estonia</Country>
<!-- other upto 100 elements -->
<Color>
</Color>
</Result>
<Result>
<Name>
</Name>
<Country>UK</Country>
<!-- other upto 100 elements -->
<Color>Red</Color>
</Result>
</All_Results>
The output produced is:
<?xml version="1.0" encoding="UTF-8"?>
<Totals>
<Name>
<Tag value="John" count="2"/>
<Tag value="Thomas" count="1"/>
</Name>
<Country>
<Tag value="UK" count="2"/>
<Tag value="US" count="1"/>
<Tag value="Estonia" count="1"/>
</Country>
<Color>
<Tag value="Red" count="2"/>
<Tag value="Green" count="1"/>
</Color>
</Totals>

Hi experts,
I have seen similar questions to mine, yet didn't find a good mach.
Please point to the right thread if exists.
I have a source Xml:
<All_Results>
<Result>
<Name>John</Name>
<Country>UK</Country>
<!-- other upto 100 elements -->
<Color>Red</Color>
</Result>
<Result>
<Name>John</Name>
<Country>US</Country>
<!-- other upto 100 elements -->
<Color>Green</Color>
</Result>
<Result>
<Name>Thomas</Name>
<Country>Estonia</Country>
<!-- other upto 100 elements -->
<Color>
</Color>
</Result>
<Result>
<Name>
</Name>
<Country>UK</Country>
<!-- other upto 100 elements -->
<Color>Red</Color>
</Result>
</All_Results>
Each <Result> has the same list of sub-elements, some might not have a
text value
I want to aggregate and get something like this:
<Totals>
<Name>
<Tag value="John" count="2" />
<Tag value="Thomas" count="1" />
</Name>
<Country>
<Tag value="UK" count="2" />
<Tag value="US" count="1" />
<Tag value="Estonia" count="1" />
</Country>
<Color>
<Tag value="Red" count="2" />
<Tag value="Green" count="1" />
</Color>
<!-- other elements grouped by element name, sorted by total of
element values-->
</Totals>
Please advice.
Thanks,
Leonid
