XSLT - Extract the value of an element dynamically

Hello,

I am trying to extract the value of an element in an XML. In the future, this can be any XML and any element. Element name is passed as a parameter to the XSL. I am using xerces. Given below is the XML and XSL that I wrote and ofcourse, it does not work. Please suggest. FYI, I am trying to retrieve the value for MAIL_OUT_PROCESS_ID (for now).

XML
------

<?xml version="1.0"?>
<MAILOUTS>
<MAILOUT>
<MAIL_OUT_ID>1234</MAIL_OUT_ID>
<MAIL_OUT_PROCESS_ID>21</MAIL_OUT_PROCESS_ID>
<PERSON_ID>835756</PERSON_ID>
<PERSON_NBR>28366</PERSON_NBR>
<FIRST_NAME>RONNIE</FIRST_NAME>
<MIDDLE_NAME>JAMES</MIDDLE_NAME>
<LAST_NAME>DIO</LAST_NAME>
<ADDRESS_LINE_1>666 HELL STREET</ADDRESS_LINE_1>
<ADDRESS_LINE_2/>
<CITY>FORT VALLEY</CITY>
<STATE>GA</STATE>
<ZIP5>30320</ZIP5>
<ZIP4>1776</ZIP4>
<COUNTY>UNKNOWN</COUNTY>
</MAILOUT>
</MAILOUTS>

---------------------------------------------------------------------------------------------------------------------------------------

XSL
----------
<xsl:stylesheet version="2.0"
      xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
      <xsl:output method="text" indent="yes" encoding="UTF-8" />

      <xsl:param name="elementName" />

      <xsl:template match="*">
            <xsl:value-of select="local-name()" />
            <xsl:if test="local-name()=$elementName">
                  <xsl:value-of select="." />
            </xsl:if>
      </xsl:template>

      <xsl:template match="comment()" />
      <xsl:template match="processing-instruction()" />

      <xsl:template match="text()" />

</xsl:stylesheet>

Thanks,

the problem you were having is that your template for match="*" stopped after processing the root node
There was no continuation in your stylesheet

I would do this a lot simpler though

<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" indent="yes" encoding="UTF-8" />
<xsl:param name="elementName" ></xsl:param>
<xsl:template match="/">
<xsl:value-of select="//*[local-name() = $elementName]"/>
</xsl:template>
</xsl:stylesheet>

cheers
