How to do this kind of message transformation?


i have flat file 4 columns: location, category, date , sales
data this:
1,toys, 2010-01-01, 100.00
1,toys, 2010-01-02, 210.00
1,food, 2010-01-01, 500.00
2,toys, 2010-01-03, 220.00

try transform file format has structure:
<dataset>
    <dimension value="1">
        <metric category="toy">
            <data date="2010-01-01" sales="100.00"/>
            <data date="2010-01-02" sales="210.00"/>
        </metric>
        <metric category="food">
            <data date="2010-01-01" sales="500.00"/>
        </metric>
    </dimension>
    <dimension value="2">
        <metric category="toy">
            <data date="2010-01-03" sales="220.00"/>
        </metric>
    </dimension>
</dataset>

reckon easy mapping, didn't figure out functoid can use apply logic.

ideas?

thank you.

hi,

i did small poc , able mapping need.  first created flatfile schema convert input text file xml , created custom xslt using muenchian method transform to the desired output.

xslt:

<

xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/xsl/transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:var="http://schemas.microsoft.com/biztalk/2003/var" exclude-result-prefixes="msxsl var" version="1.0">

<xsl:output omit-xml-declaration="yes" indent="yes" method="xml" version="1.0"/>

<xsl:key name="group" match="/*[local-name()='root' , namespace-uri()='http://testproject.ffsale']/*[local-name()='dataset' , namespace-uri()='']" use="concat(dimension, category)"/>

<xsl:template match="/">

<xsl:apply-templates select="/*[local-name()='root' , namespace-uri()='http://testproject.ffsale']"/>

</xsl:template>

<xsl:template match="/*[local-name()='root' , namespace-uri()='http://testproject.ffsale']">

<dataset>

<xsl:for-each select="/*[local-name()='root' , namespace-uri()='http://testproject.ffsale']/*[local-name()='dataset' , namespace-uri()=''][generate-id()=generate-id(key('group', concat(dimension, category))[1])]">

<dimension>

<xsl:attribute name="value"><xsl:value-of select="dimension"/></xsl:attribute>

<metric>

<xsl:attribute name="category"><xsl:value-of select="category"/></xsl:attribute>

<xsl:for-each select="key('group', concat(dimension, category))">

<data>

<xsl:attribute name="date"><xsl:value-of select="date"/></xsl:attribute>

<xsl:attribute name="sales"><xsl:value-of select="sales"/></xsl:attribute>

</data>

</xsl:for-each>

</metric>

</dimension>

</xsl:for-each>

</dataset>

</xsl:template>

</

xsl:stylesheet>


testing: tested above xslt using following input message.  please see results in output message.

input message:

<

root xmlns="http://testproject.ffsale">

<dataset xmlns="">

<dimension>1</dimension>

<category>toys</category>

<date> 2010-01-01</date>

<sales> 100.00</sales>

</dataset>

<dataset xmlns="">

<dimension>1</dimension>

<category>toys</category>

<date> 2010-01-02</date>

<sales> 210.00</sales>

</dataset>

<dataset xmlns="">

<dimension>2</dimension>

<category>toys</category>

<date> 2010-01-03</date>

<sales> 220.00</sales>

</dataset>

</
