Sorry, I meant match="element" use="../element"

I also made an error in the named template. Here's an example that I tested.
The stylesheet looks for 'DOB' but because DOB is in the mapping file as being
equivalent to DateOfBirth, data can be obtained from the DateOfBirth element
in the source tree.

customer.xml
=============
<Customer>
  <Name>Amit</Name>
  <DateOfBirth>01/01/1970</DateOfBirth>
  <ZipCode>12121</ZipCode>
</Customer>


equivelem.xml
=============
<sourceMappings>
  <equivalentElementNames>   
    <element>DOB</element>
    <element>DateOfBirth</element>
  </equivalentElementNames>
  <equivalentElementNames>  
    <element>ZipCode</element>
    <element>PostCode</element>
  </equivalentElementNames>
</sourceMappings>


test.xsl
=============
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

  <xsl:output method="xml" indent="no"/>

  <xsl:key name="equiv" match="element" use="../element"/>

  <xsl:variable name="mappings" select="document('equivelem.xml')/sourceMappings"/>

  <xsl:template match="Customer">
    <result>
      <xsl:call-template name="get-childElem-stringValue">
        <xsl:with-param name="childElem-name" select="'DOB'"/>
      </xsl:call-template>
    </result>
  </xsl:template>

  <xsl:template name="get-childElem-stringValue">
    <xsl:param name="childElem-name"/>
    <xsl:variable name="currentNode" select="."/>
    <xsl:for-each select="$mappings">
      <xsl:variable name="elements" select="key('equiv',$childElem-name)"/>
      <xsl:value-of select="$currentNode/*[local-name()=$elements]"/>
    </xsl:for-each>
  </xsl:template>

</xsl:stylesheet>



result of applying test.xsl to customer.xml with Saxon 6.5.2:
=============================================================
<?xml version="1.0" encoding="utf-8"?><result>01/01/1970</result>
