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,

just change this one template

    <xsl:template match="*">
        <xsl:choose>
            <xsl:when test="local-name()  = $elementName">
                <xsl:value-of select="." />
            </xsl:when>
            <xsl:otherwise>
                <xsl:apply-templates/>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>

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
