XSLT 1.0 Duplikate entfernen

[juls_pro_37]

Hallo zusammen,

bitte um Info, was in meinem Code nicht korrekt ist. -> Benötige keine Duplikate von "TEXT_LINE" unter GRP.

Hier mein XSLT:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl">
    <xsl:output method="xml" indent="yes"/>
	<xsl:template match="HeaderText[generate-id() != generate-id(key('header_text', TEXT_LINE)[1])]" />

<xsl:template match="GRP">
    <xsl:copy>	
		<!--copy content of TXT_001 to GRP, so it can be used to set symbol at SalesTable -->
      <xsl:for-each select="./TXT_001">
            <xsl:if test="./TEXT_LINE != ''">                
				<TEXT_LINE>
					<xsl:text>yes</xsl:text>
				</TEXT_LINE>
            </xsl:if>
        </xsl:for-each>
    <!--copy all other nodes-->
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>     
  
 <xsl:template match="HeaderText[generate-id() != generate-id(key('header_text', TEXT_LINE)[1])]" />
 
   <!-- delete empty nodes -->
 <xsl:template match="node()|@*">
     <xsl:copy>
       <xsl:apply-templates select="node()|@*"/>
     </xsl:copy>
 </xsl:template>
 <xsl:template match="*[not(@*|*|comment()|processing-instruction()) and normalize-space()='']"/>
<!-- delete empty nodes -->  
  
</xsl:stylesheet>

und hier mein XML:

<?xml version="1.0"?>
<SEEDELFOR>
	<CNT>		
		<GRP>			
			<REF_ON>12345</REF_ON>	
			<TXT_001>
				<QUALIFIER>ZZZ</QUALIFIER>
				<TEXT_LINE> Test1</TEXT_LINE>
			</TXT_001>
			<TXT_001>
				<QUALIFIER>PUR</QUALIFIER>
				<TEXT_LINE> Test2</TEXT_LINE>
			</TXT_001>			
			<ITEM>
				<ITEM_NUMBER_EN>1234556789123</ITEM_NUMBER_EN>				
			</ITEM>			
		</GRP>
	</CNT>
</SEEDELFOR>

Danke & LG Julin
