I have a XML that I need to map.
The XML goes like:

<Children>
<Child>
<References>
<External>
<Reference name="filename" value="1.dat"/>
<Reference name="invoicenr" value="1111111"/>
<Reference name="invoicer_name" value="Bill"/>
<Reference name="invoiceref" value="bbbbbb"/>
</External>
</References>
</Child>
<Child>
<References>
<External>
<Reference name="filename" value="2.dat"/>
<Reference name="invoicenr" value="222222"/>
<Reference name="invoicer_name" value="Bill"/>
<Reference name="invoiceref" value="bbbbbb"/>
</External>
</References>
</Child>
<Child>
<References>
<External>
<Reference name="filename" value="3.dat"/>
<Reference name="invoicenr" value="33333"/>
<Reference name="invoicer_name" value="Clinton"/>
<Reference name="invoiceref" value="ccccc"/>
</External>
</References>
</Child>
</Children>

I want the structure to map to:

<Senders>
<Sender>
<invoicer_name>Bill</invoicer_name>
<invoiceref>bbbbbb</invoiceref>
<Items TotalItems="2"/>
</Sender>
<Sender>
<invoicer_name>Clinton</invoicer_name>
<invoiceref>ccccc</invoiceref>
<Items TotalItems="1"/>
</Sender>
</Senders>

I have tried to use the "Muenchian Grouping" method, but am not able to
obtain both
<invoicer_name> and <invoiceref> under the <Sender> tag

Here is my xsl :

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:output encoding="ISO-8859-1"/>
<xsl:key name="kDistinctSender"
match="Children/Child/References/External/Reference[@name='invoicer_name']/@
value" use="."/>
<xsl:template match="/">
<Senders>
<!-- go through distinct InvoicerName -->
<xsl:for-each
select="/Children/Child/References/External/Reference[@name='invoicer_name']
/@value[generate-id()=generate-id(key('kDistinctSender',.))]">
<!-- sort by InvoicerName -->
<xsl:sort select="."/>
<Sender>
<xsl:variable name="InvoicerName">
<xsl:value-of select="."/>
</xsl:variable>
<InvoicerName>
<xsl:value-of select="$InvoicerName"/>
</InvoicerName>
<Items TotalItems="{count(key('kDistinctSender',.))}">
</Items>
</Sender>
</xsl:for-each>
</Senders>
</xsl:template>
</xsl:stylesheet>

re: Help on xslt - grouping

Specify for the "use" attribute of xsl:key the concatenation of the values
of "invoicer_name" and "invoiceref".

re: Help on xslt - grouping

Thanks
I have tried to play around with concatenation and cant get it right, her is
the result :

<Senders>
<Sender>
<InvoicerName>Bill</InvoicerName>
<Items TotalItems="3"/>
</Sender>
</Senders>


Using xsl :

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:output encoding="ISO-8859-1"/>
<xsl:key name="kDistinctSender"
match="Children/Child/References/External/Reference[@name='invoicer_name']/@
value" use="concat(@name,'||',@value)"/>
<xsl:template match="/">
<Senders>

<xsl:for-each
select="/Children/Child/References/External/Reference[@name='invoicer_name']
/@value[generate-id()=generate-id(key('kDistinctSender',concat(@name,'||',@v
alue)))]">

<xsl:sort select="."/>
<Sender>
<xsl:variable name="InvoicerName">
<xsl:value-of select="."/>
</xsl:variable>
<InvoicerName>
<xsl:value-of select="$InvoicerName"/>
</InvoicerName>
<Items
TotalItems="{count(key('kDistinctSender',concat(@n ame,'||',@value)))}">
</Items>
</Sender>
</xsl:for-each>
</Senders>
</xsl:template>
</xsl:stylesheet>

Did you try to simply put them in the right order?


<xsl:template match="/">
<Senders>
<!-- go through distinct InvoicerName -->
<xsl:apply-templates select="-XPath expression-">
</Senders>
</xsl:template>

<xsl:template match="-expression from above-">
<Sender>
<xsl:apply-templates select=".[@name='invoicer_name']"/>
<xsl:apply-templates select=".[@name='invoiceref']"/>
<xsl:apply-templates select=".[@name='otherArtributeName']"/>
<xsl:apply-templates select=".[@name='............']"/>
<xsl:apply-templates select=".[@name='-one more line-']"/>
</Sender>
</xsl:apply-templates>
</xsl:template>

<xsl:........... - And Some More Templates - ........./>

This transformation:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>

<xsl:strip-space elements="*"/>

<xsl:key name="kExtNameRef" match="External"
use="concat(Reference[@name='invoicer_name']/@value,
'+',
Reference[@name='invoiceref']/@value
)"/>
<xsl:template match="/">
<Senders>
<xsl:for-each select=
"/*/*/*/External
[generate-id()
=
generate-id(
key('kExtNameRef',
concat(Reference[@name='invoicer_name']/@value,
'+',
Reference[@name='invoiceref']/@value
)
)[1]
)
]">
<Sender>
<invoicer_name>
<xsl:value-of select=
"Reference[@name='invoicer_name']/@value"/>
</invoicer_name>
<invoiceref>
<xsl:value-of select=
"Reference[@name='invoiceref']/@value"/>
</invoiceref>
<Items TotalItems="{
count(
key('kExtNameRef',
concat(Reference[@name='invoicer_name']/@value,
'+',
Reference[@name='invoiceref']/@value
)
)
)
}"/>
</Sender>
</xsl:for-each>
</Senders>

</xsl:template>
</xsl:stylesheet>

when applied on your source.xml:

<Children>
<Child>
<References>
<External>
<Reference name="filename" value="1.dat"/>
<Reference name="invoicenr" value="1111111"/>
<Reference name="invoicer_name" value="Bill"/>
<Reference name="invoiceref" value="bbbbbb"/>
</External>
</References>
</Child>
<Child>
<References>
<External>
<Reference name="filename" value="2.dat"/>
<Reference name="invoicenr" value="222222"/>
<Reference name="invoicer_name" value="Bill"/>
<Reference name="invoiceref" value="bbbbbb"/>
</External>
</References>
</Child>
<Child>
<References>
<External>
<Reference name="filename" value="3.dat"/>
<Reference name="invoicenr" value="33333"/>
<Reference name="invoicer_name" value="Clinton"/>
<Reference name="invoiceref" value="ccccc"/>
</External>
</References>
</Child>
</Children>

produces the wanted result:

<Senders>
<Sender>
<invoicer_name>Bill</invoicer_name>
<invoiceref>bbbbbb</invoiceref>
<Items TotalItems="2" />
</Sender>
<Sender>
<invoicer_name>Clinton</invoicer_name>
<invoiceref>ccccc</invoiceref>
<Items TotalItems="1" />
</Sender>
</Senders>


Hope this helped.

re: Help on xslt - grouping

This is great, exactly what I want. Thank you.
This is goanna be tested in QA 22. Mai and if successful, put into
production on 25. Mai where the
xsl will do transformation on files that are as big as 100MB with thousands
of items

Good luck, and it would be interesting if you share your experience (or if
you have any problems -- just signal) to the newsgroups (and the xsl-list).
