Create multiple line item from one line item in BizTalk mapping

Question

Hi,
In one of our new requirement we need to create 3 line items for every line item we are receiving with same value but in the below format.
Sample Input:
<EmpId>1234</EmpId><Name>ABCD></Name><Dept>YYY</Dept><Year>2014</Year><Desc1>D1</Desc1><Desc2>D2</Desc2><Desc3>D3</Desc3><Valid>Yes</Valid>
Sample Output in Flatfile:
1234,ABCD,,,D1,Yes
1234,ABCD,YYY,,D2,Yes
1234,ABCD,YYY,2014,D3,Yes
Can you Pls help me in creating the mapping in above format.
Thanks in advance,
Regards,

Elango,
Before I explain about the solution, make sure when you give inputs/requirement in forums for us to help you, pay attention.
The input instance you have shown
Doesn’t have a root element
Has a typo - <Name>ABCD></Name> -Element has invalid “>” character.
This makes us to spend more time in cleansing your input and then find out solution.
We are here to help you, so help us to help you better.
Anyway, coming to the solution
You have to create map with a structure similar to the below shown image:
Here destination schema is a flat file schema with comma-delimited fields.
If you look into the destination schema, it look similar to your input schema, but there is just one “Desc” field instead of “Desc1”, “Desc2”, “Desc3” in your source schema. In destination, the
record has to repeat with same values for rest of the fields. And for “Desc” in destination schema will have corresponding index value of “Desc1” or “Desc2” or “Desc3” from source. i.e. first node of destination will have value of “Desc1” from source to “Desc”
field in destination, second node of destination will have value of “Desc2” from source to “Desc” field in destination and third node of destination will have value of “Desc3” from source to “Desc” field in destination.
I use XSLT in the map, with recursive template which will repeat for 3 times. I have given comment in the XSLT for your benefit.
<?xml version="1.0" encoding="UTF-16"?>
<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" method="xml" version="1.0" />
<xsl:template match="/">
<xsl:apply-templates select="/Root" />
</xsl:template>
<xsl:template match="/Root">
<Record>
<!--Call the template with index and counter of 3. There times as you wanted for every item-->
<xsl:call-template name="LintItemTemp">
<xsl:with-param name="i">1</xsl:with-param>
<xsl:with-param name="count">3</xsl:with-param>
</xsl:call-template>
</Record>
</xsl:template>
<xsl:template name="LintItemTemp">
<xsl:param name="i" />
<xsl:param name="count" />
<Details>
<EmpId>
<xsl:value-of select="EmpId/text()" />
</EmpId>
<Name>
<xsl:value-of select="Name/text()" />
</Name>
<Dept>
<xsl:value-of select="Dept/text()" />
</Dept>
<Year>
<xsl:value-of select="Year/text()" />
</Year>
<!--as in your output instance, Lineitem1 will have value of Desc1-->
<xsl:if test ="($i =1)">
<Desc>
<xsl:value-of select="Desc1/text()" />
</Desc>
</xsl:if>
<!--as in your output instance, Lineitem2 will have value of Desc3-->
<xsl:if test ="($i =2)">
<Desc>
<xsl:value-of select="Desc2/text()" />
</Desc>
</xsl:if>
<!--as in your output instance, Lineitem3 will have value of Desc3-->
<xsl:if test ="($i =3)">
<Desc>
<xsl:value-of select="Desc3/text()" />
</Desc>
</xsl:if>
<Valid>
<xsl:value-of select="Valid/text()" />
</Valid>
<xsl:value-of select="./text()" />
</Details>
<!--Recursive template, i.e. calling the template again for 3 times as your requirement-->
<xsl:if test="$i &lt; $count">
<xsl:call-template name="LintItemTemp">
<xsl:with-param name="i">
<xsl:value-of select="$i + 1"/>
</xsl:with-param>
<xsl:with-param name="count">
<xsl:value-of select="$count"/>
</xsl:with-param>
</xsl:call-template>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
So the input and output will look like the below:
You can change the schema/XSLT and its corresponding namespaces as you want.
When the above shown output is send to a custom-pipeline with flat file assembler in send port will output the above shown output to the flat-file structure as you wanted. Again, I repeat you
to use flat-file file schema with comma-delimited fields as the destination schema in the above shown map for you to get the flat-file output as you needed.
