Condition on Mapping in Repeating Records

Question

Hi,
This is my map file :
My input file is as follows:
<ns0:Root xmlns:ns0="http://schemas.microsoft.com/BizTalk/2003/aggschema">
  <InputMessagePart_0>
    <ns1:Response xmlns:ns1="http://Interplx_ndPhase.SourceSchema">
      <Employees>
        <Employee>
          <EmpID>10</EmpID>
          <EmpName>Prakash</EmpName>
        </Employee>
       <Employee>
          <EmpID>20</EmpID>
          <EmpName>EmpName_0</EmpName>
        </Employee>
      </Employees>
    </ns1:Response>
  </InputMessagePart_0>
  <InputMessagePart_1>
    <ns2:ResponseM xmlns:ns2="http://Interplx_ndPhase.ManagerSchema">
      <Managers>
        <Manager>
          <ManagerID>30</ManagerID>
          <Salary>Salary_0</Salary>
        </Manager>
        <Manager>
          <ManagerID>20</ManagerID>
          <Salary>1000000</Salary>
        </Manager>
      </Managers>
    </ns2:ResponseM>
  </InputMessagePart_1>
</ns0:Root>
I want to compare each EmpID with each Manager ID.If any  EmpID and ManagerID is equal then simply transform with destination schema otherwise not.
How its is possible ??
Please suggest me some solution.

For the given input instance, if you want map the employees who are managers (i.e. for the employee whose EmployeeID matches with the ManagerID) I created a output schema like the below to give an idea about the XSLT (which you can change it to
yours)
, in the map, If I use the XSLT like the following:
<?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 s0" version="1.0" xmlns:s0="http://Interplx_ndPhase.ManagerSchema" xmlns:ns0="http://schemas.microsoft.com/BizTalk/2003/aggschema" xmlns:ns2="http://Interplx_ndPhase.SourceSchema">
<xsl:output omit-xml-declaration="yes" method="xml" version="1.0" />
<xsl:template match="/">
<xsl:apply-templates select="/ns0:Root" />
</xsl:template>
<xsl:template match="/ns0:Root">
<ns0:Root>
<OutputMessagePart_0>
<ns2:Response>
<Employees>
<xsl:for-each select="InputMessagePart_0/ns2:Response/Employees/Employee">
<Employee>
<xsl:call-template name="CheckMan">
<xsl:with-param name="empID" select="EmpID/text()" />
<xsl:with-param name="pos" select="position()" />
</xsl:call-template>
</Employee>
</xsl:for-each>
</Employees>
</ns2:Response>
</OutputMessagePart_0>
</ns0:Root>
</xsl:template>
<xsl:template name="CheckMan">
<xsl:param name="empID" />
<xsl:param name="pos" />
<xsl:for-each select="../../../../InputMessagePart_1/s0:ResponseM/Managers/Manager">
<xsl:if test="ManagerID/text() = $empID">
<EmpID>
<xsl:value-of select="../../../../InputMessagePart_0/ns2:Response/Employees/Employee[$pos]/EmpID/text()" />
</EmpID>
<EmpName>
<xsl:value-of select="../../../../InputMessagePart_0/ns2:Response/Employees/Employee[$pos]/EmpName/text()" />
</EmpName>
</xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
You would get the desired output. As mentioned, you can change the output as per your need, and this XSLT which works for me for the above input & output schema can give an idea about how to achieve this requirement.
