Requirement-"The stylesheet should be modified not to add DUCK(product type) if there exists one with the same action(product action)".
ie how can i write validation in XSLT to add a DUCK if and only if the product action is different. In the xml given below the action of two products is "Add". For the stylesheet sholud not add DUCK
The XSLT is
<?xml version="1.0" encoding="iso-8859-1" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:invoker="http://xml.apache.org/xalan/java/vf.bis.xsltc.ServiceInvoker" exclude-result-prefixes="xs xsi invoker">
<xsl:output method="xml" omit-xml-declaration="yes" encoding="iso-8859-1" indent="yes" />
<xsl:template match="/ | @* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="product[count(./GetInfoOutput)>0]">
<!-- DUCK product
-->
<xsl:if test="count(./GetInfoOutput/lovRecords[key1='DUCK'])>0">
<xsl:element name="product">
<xsl:attribute name="id">
<xsl:value-of disable-output-escaping="yes" select="invoker:GenerateUUID()" />
</xsl:attribute>
<xsl:attribute name="parentId">
<xsl:value-of select="./@parentId" />
</xsl:attribute>
<xsl:attribute name="customerId">
<xsl:value-of select="./@customerId" />
</xsl:attribute>
<xsl:attribute name="type">

</xsl:attribute>
<xsl:attribute name="name">

</xsl:attribute>
<xsl:attribute name="provider">

</xsl:attribute>
<xsl:element name="parameter">

</xsl:element>
<xsl:element name="parameter">
<xsl:attribute name="name">Product Type</xsl:attribute>
<xsl:value-of select="./GetInfoOutput/lovRecords[key1='DUCK']/key1" />
</xsl:element>
<xsl:element name="parameter">
<xsl:attribute name="name">Network Command</xsl:attribute>

<xsl:element name="action">

<xsl:value-of select="./action/@name" />
</xsl:attribute>
</xsl:element>
</xsl:element>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
The XML looks like this
