How to map single to multiple record in Biztalk Map

Question

Hi,
I have a flat file Input as below
For understandability I am making it as XML:
<Input>
<Name>vignesh</Name>
<Country>India</Country>
<orderNumber>123<orderNumber>
</Input>
I am having a look up table to retrieve multiple LineItem per Name
Output expected 
I need to repeat the record based on the table as
<Output>
<Detail>
<Name>vignesh</Name>
<LineItems>38</LineItems>
</Detail>
<Detail>
<Name>vignesh</Name>
<LineItems>45</LineItems>
</Detail>
<Detail>
<Name>vignesh</Name>
<LineItems>88</LineItems>
</Detail>
<Detail>
<Name>vignesh</Name>
<LineItems>99</LineItems>
</Detail>
<Detail>
<Name>vignesh</Name>
<LineItems>85</LineItems>
</Detail>
</Output>
I have created an external assembly to pull the data from database and concatenating the lineitems in a string as (38,45,88,99,85). Now either I need to use map functoids/inline xslt's.
Please help to move further with some samples.

Hi Vignesh,
Add a scripting functiod as shown here in the image, in the scripting functiod call "Inline XSLT Call Template". This scripting functiod would have two parameters.
1- Name link from the soruce schema. 2- Output something like "38,45,88,99,85" (without quotes). This could be link from the functiod which pulls the data from db. In my case, I just used a string fuctiod which would output
38,45,88,99,85 to the scripting functiod.
In the scripting fuctiod, use the below XSLT template. I have commented the XSLT to detail how it works:
<xsl:template name="ConstructDetailNodeTemplate">
<xsl:param name="name" />
<xsl:param name="value" />
<xsl:variable name="NameFromSoruce" select="$name"></xsl:variable>
<!-- call splitter template which accepts the "," separated string -->
<xsl:call-template name="StringSplit">
<xsl:with-param name="nam" select="$NameFromSoruce" />
<xsl:with-param name="val" select="$value" />
</xsl:call-template>
</xsl:template>
<xsl:template name="StringSplit">
<xsl:param name="nam" />
<xsl:param name="val" />
<!-- do a check to see if the input string (still) has a "," in it -->
<xsl:choose>
<xsl:when test="contains($val, ',')">
<Detail>
<Name>
<xsl:value-of select="$nam"/>
</Name>
<!-- pull out the value of the string before the "," delimiter -->
<LineItems><xsl:value-of select="substring-before($val, ',')" /></LineItems>
</Detail>
<!-- recursively call this template and pass in
value AFTER the "," delimiter -->
<xsl:call-template name="StringSplit">
<xsl:with-param name="nam" select="$nam" />
<xsl:with-param name="val" select="substring-after($val, ',')" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<!-- if there is no more delimiter values, print out
the whole string -->
<Detail>
<Name>
<xsl:value-of select="$nam" />
</Name>
<LineItems>
<xsl:value-of select="$val" />
</LineItems>
</Detail>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
The output would look like this as you wanted for the above your input:
