Biztalk Map create duplicate target node

Question

Using biztalk mapper, I need a target node to be duplicated.. I have created a simplified version of my issue. Please see below map link for source and destination schema... Ooopps sorry, not enough points to post images..

I need the target Option node to be duplicated for each OptionNotes. The value of OptionNotes is to be split by a pipe ("|"), then map to target Code and Description.

The input is as below:

<ns0:Source xmlns:ns0="http://Test.SOAP.Source1">
  <Option>
    <OptionID>ID0_NoNotes</OptionID>
    <OptionName>OptionName_0</OptionName>
  </Option>
  <Option>
    <OptionID>ID1_NoNotes</OptionID>
    <OptionName>OptionName_1</OptionName>
    <OptionNotes>NOTE1|BLAH1</OptionNotes>
    <OptionNotes>NOTE2|BLAH2</OptionNotes>
  </Option>  
</ns0:Source>

The output should be as below:

<Destination>
    <Options>
        <Option>
            <Code>ID0_NoNotes</Code>
            <Description>OptionName_0</Description>
        </Option>
        <Option>
            <Code>ID1_NoNotes</Code>
            <Description>OptionName_1</Description>
        </Option>
        <Option>
            <Code>NOTE1</Code>
            <Description>BLAH1</Description>
        </Option>
        <Option>
            <Code>NOTE2</Code>
            <Description>BLAH2</Description>
        </Option>       
    </Options>
</Destination>

Tried to use Looping and combination with Value Mapping, but to no avail. Do I have to resort to inline xslt?

(I know nothing about BizTalk.) Why wouldn't you use XSLT to transform XML? That's what it is for. — michael.hor257k
As an avid BizTalker, I NEVER use the mapper, always XSLT, but then again the question is on the mapper, not how to do it in XSLT. — Pieter Vandenheede
@michael.hor257k sorry, thought this touches xslt. I'll remove the xslt tag. — Joe Suharjo

We have used Mapforce, which has done this easily. We then get the XSLT and import it as part of Inline XSLT scripting functoid.

The XSLT produced was as below:

<xsl:for-each select="ns0:Source/Option">
<Option>
<xsl:for-each select="OptionID">
<Code>
<xsl:value-of select="string(.)"/>
</Code>
</xsl:for-each>
<xsl:for-each select="OptionName">
<Description>
<xsl:value-of select="string(.)"/>
</Description>
</xsl:for-each>
</Option>
</xsl:for-each>
<xsl:for-each select="ns0:Source/Option/OptionNotes">
<xsl:variable name="var1_resultof_cast" select="string(.)"/>
<Option>
<Code>
<xsl:value-of select="substring-before($var1_resultof_cast, '|')"/>
</Code>
<Description>
<xsl:value-of select="substring-after($var1_resultof_cast, '|')"/>
</Description>
</Option>
</xsl:for-each>

Thanks everyone.
