Hi there i am writing an xslt but it has a repeating result/output which is not expected.

Please help me to debug the code. See code below

===============================================
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:variable name="count_package_disc"
                select="//htcBusinessDoc/payload/htcBase/sites/site/lineOrder/lineItem[lineAction='DISCONNECT']/isp/pacakge"/>
<xsl:variable name="count_package_inst"
                select="//htcBusinessDoc/payload/htcBase/sites/site/lineOrder/lineItem[lineAction='INSTALL']/isp/pacakge"/>

<xsl:variable name="disc_action"
                select="//htcBusinessDoc/payload/htcBase/sites/site/lineOrder/lineItem[lineAction='DISCONNECT']/isp/pacakge/action/text()"/>
<xsl:variable name="inst_action"
                select="//htcBusinessDoc/payload/htcBase/sites/site/lineOrder/lineItem[lineAction='INSTALL']/isp/pacakge/action/text()"/>

<xsl:variable name="disc_packid"
                select="//htcBusinessDoc/payload/htcBase/sites/site/lineOrder/lineItem[lineAction='DISCONNECT']/isp/pacakge/packageId/text()"/>
<xsl:variable name="inst_packid"
                select="//htcBusinessDoc/payload/htcBase/sites/site/lineOrder/lineItem[lineAction='INSTALL']/isp/pacakge/packageId/text()"/>

<xsl:template match="/">
    <xsl:choose>
    <xsl:when test="count($count_package_disc) = count($count_package_inst)">
        <xsl:for-each select="$disc_action">
             <xsl:for-each select="$inst_action">
                <xsl:if test="$disc_action = 'DISCON'">
                <xsl:if test="$inst_action = 'ADD'">
                   <xsl:if test="$disc_packid = $inst_packid">

                   <xsl:value-of select="/htcBusinessDoc/header/serviceAction"/>
                   <xsl:value-of select="/htcBusinessDoc/header/orderType"/>

                   </xsl:if>
                </xsl:if>
                </xsl:if>

           </xsl:for-each>
        </xsl:for-each>

        </xsl:when>
        <xsl:otherwise>
           Not PASSED
        </xsl:otherwise>
         </xsl:choose>
</xsl:template>

</xsl:stylesheet>
================================================== ==========

Writing Software Application is just setting instructions to the code and there is nothing impossible.

I'm not sure why you find the repetition unexpected. When you do

        <xsl:for-each select="$disc_action">
             <xsl:for-each select="$inst_action">


you are processing all the inst_action elements repeatedly - you process them all for hte first disc_action, then again for the second, and so on. Then your condition

<xsl:if test="$disc_packid = $inst_packid">


uses variables whose values don't depend at all on the current nodes you are processing in the two for-each loops.

You don't want all these global variables, you want to select nodes relative to the context node.

Without knowing your data model I can't be more specific.

Hi Michael-

Here is the link of the xml,

Thanks for your help.

Your best bet is to use the "reply to topic" and copy and paste your xml with the # (code)
