Hi All,

There is a query for which i am seeing assistance, on how to group the XML by keyElements using XSLT. Below is the sample XML code: -
<?xml version = "1.0" encoding = "UTF-8"?>

As we can see in the above XML example, there are multiple <BaseShipmentModule> tag and within each <BaseShipmentModule> we have a tag called: <Sfromlocation> and <Stolocation> which stands for location code, from and to location.



Now if we observe a little bit, we have a total of 4 <BaseShipmentModule> tag and the value for <Sfromlocation> and <Stolocation> in same in the 1st and 2nd <BaseShipmentModule> tag. Where as the value for <Sfromlocation> and <Stolocation> is same in the 3rd and 4th <BaseShipmentModule> tag. Looking for to group the XML based on the <Sfromlocation> and <Stolocation>.



Expected output is shown below: -

<?xml version = "1.0" encoding = "UTF-8"?>
<CISDocument>
<Aheader>
<OperationName>APINAME</OperationName>
</Aheader>

</Entity>


As we can see in the above result, we have combined the <ShipUnitModule> based on the <Sfromlocation> and <Stolocation> tag. And he tag <Container> has been grouped and the rest of the tag <S1> is unaffected by it. We did get help from one of the Engineers (Michael), with the below XSLT,


<xsl:stylesheet version="2.0" xmlns:xsl= <xsl:eek:utput method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/Entity">
<xsl:copy>
<xsl:for-each-group select="Shipment" group-by="concat(shipFromLocation, '|', shipToLocation)">
<Shipment>
<xsl:copy-of select="shipFromLocation, shipToLocation"/>
<xsl:copy-of select="current-group()/container"/>
</Shipment>
</xsl:for-each-group>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>


But, it is not able to help the overall output, please do help us here. Its quite important. Any suggestion will matter a lot.
 
198709km,

If I understood correctly your requirements, this will put you closer.

Code:
<xsl:stylesheet version="2.0" xmlns:xsl="[URL unfurl="true"]http://www.w3.org/1999/XSL/Transform">[/URL]
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
    <xsl:template match="/">
        <fragment><xsl:apply-templates select="//Entity"/></fragment>
    </xsl:template>
    <xsl:template match="Entity">
        <Entity>
            <Load>
                <xsl:apply-templates select="Load/BaseShipmentModule[1]" mode="first"/>
                <xsl:for-each-group select="Load/BaseShipmentModule" group-by="concat(ShipUnitModule/Sfromlocation, '|', ShipUnitModule/Stolocation)">
                    <BaseShipmentModule>
                        <ShipUnitModule>
                            <xsl:copy-of select="current-group()/ShipUnitModule/Shnum"/>
                            <xsl:copy-of select="(current-group()/ShipUnitModule/Sfromlocation)[1], (current-group()/ShipUnitModule/Stolocation)[1]"/>
                            <xsl:copy-of select="current-group()/ShipUnitModule/Container"/>
                        </ShipUnitModule>
                     </BaseShipmentModule>
               </xsl:for-each-group>
                <xsl:apply-templates select="Load/BaseShipmentModule[position() = last()]" mode="last"/>
            </Load>
        </Entity>
    </xsl:template>
    <xsl:template match="BaseShipmentModule" mode="first">
        <xsl:copy-of select="preceding-sibling::*"/>
    </xsl:template>
    <xsl:template match="BaseShipmentModule" mode="last">
        <xsl:copy-of select="following-sibling::*"/>
    </xsl:template>
</xsl:stylesheet>

Note: I only took care of the Entity element. The rest is up to you.
