Hi,

I am trying to perform an XSL transform for an XML
Document to remove duplicate Nodes. The XML file is as
below

<Test>
  <Text LineCount="29" Object="RECORD" Status="?"
Version="000">
    <Text.Description><![CDATA[Table
File]]></Text.Description>
    <Text.LongDescription><![CDATA[Table
File]]></Text.LongDescription>
  </Text>

  <Text LineCount="29" Object="RECORD" Status="?"
Version="000">
    <Text.Description><![CDATA[Table
File]]></Text.Description>
    <Text.LongDescription><![CDATA[Table
File]]></Text.LongDescription>
  </Text>
</Test>


The XSL stylesheet I am using to do this is as below.

<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
version="1.0" >
  <xsl:output method="xml"
omit-xml-declaration="yes"/>
   <xsl:template match="Text">
      <xsl:if test="not(@Object =
preceding::Text/@Object)">
        <xsl:copy>
          <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
      </xsl:if>
   </xsl:template>
   
    <xsl:template match="@*|node()">
      <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
      </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

The output generated removes the duplicate node but
somehow doesn't process the CDATA sections properly.

<Test>
  <Text LineCount="29" Object="RECORD" Status="?"
Version="000">
    &lt;![CDATA[<Text.Description>]]&gt;Table
File</Text.Description>
    &lt;![CDATA[<Text.LongDescription>]]&gt;Table
File</Text.LongDescription>
  </Text>  
</Test>

I have tried adding a "cdata-section-elements" section
to the xsl:ouput tag telling it to treat
Text.Description & Text.LongDescription as CDATA.
This creates the following output

<Test>
  <Text LineCount="29" Object="RECORD" Status="?"
Version="000">
   
&lt;![CDATA[<Text.Description><![CDATA[]]]]><![CDATA[>]]><![CDATA[Table
File]]></Text.Description>
   
&lt;![CDATA[<Text.LongDescription><![CDATA[]]]]><![CDATA[>]]><![CDATA[Table
File]]></Text.LongDescription>
  </Text>
</Test>  

Can anyone help me?

Cheers
Rohit.
