XSLT . call another template with xsl:param - xslt

Question

I am new to xslt and trying to create one XSLT ,
I am calling aother template with passing param value to it
But somehow blank value is coming in param variable for destination template.
Here is the simplified sample xml file :
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<TCXML xmlns="http://www.tcxml.org/Schemas/TCXMLSchema">
<BOMWindow elemId="id62" revision_rule="id60" top_line="id2">
<GSIdentity elemId="id1" label="a00pC7EtM1CZ7D"/>
</BOMWindow>
<IMAN_Drawing elemId="id78" owning_site="id4" primary_object="#id21" secondary_object="#id25" user_data="">
<GSIdentity elemId="id50" label="R8D9sTvgBT4jNA"/>
</IMAN_Drawing>
<IMAN_Drawing elemId="id79" owning_site="#id4" primary_object="#id22" secondary_object="#id26" user_data="">
<GSIdentity elemId="id56" label="R8D9sTfVBT4jNA"/>
</IMAN_Drawing>
<IMAN_Drawing elemId="id80" owning_site="#id4" primary_object="#id20" secondary_object="#id24" user_data="">
<GSIdentity elemId="id44" label="R8A9sTu6BT4jNA"/>
</IMAN_Drawing>
<UGPART creation_date="2012-06-05T09:25:30Z" date_released="2012-06-05T09:25:33Z" ead_paragraph="" elemId="id117" format_used="PART" gov_classification="" object_name="Test" owning_organization="" >
<GSIdentity elemId="id21" label="RXM9sPifBT4jNA"/>
</UGPART>
<UGPART creation_date="2012-06-05T09:25:30Z" date_released="2012-06-05T09:25:33Z" ead_paragraph="" elemId="id117" format_used="PART" gov_classification="" object_name="Test2" owning_organization="" >
<GSIdentity elemId="id20" label="R3K9sPifBT4jNA"/>
</UGPART>
<UGPART creation_date="2012-06-05T09:25:30Z" date_released="2012-06-05T09:25:33Z" ead_paragraph="" elemId="id117" format_used="PART" gov_classification="" object_name="Test3" owning_organization="" >
<GSIdentity elemId="id22" label="xuO9sPifBT4jNA"/>
</UGPART>
In XML there are 3 IMAN_Drawing tags, and 3 UGPART tags
Here is my xslt for this
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:plm="http://www.tcxml.org/Schemas/TCXMLSchema" version="1.0">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
<xsl:template match="/plm:TCXML/plm:IMAN_Drawing">
<xsl:copy>
<xsl:copy-of select="#*" />
<xsl:for-each select="/plm:TCXML/plm:IMAN_Drawing">
<xsl:variable name="currentSecObjectId" select="#secondary_object"/>
<xsl:variable name="RefSecObjectId" select="substring($currentSecObjectId,2)"/>
<xsl:variable name="currentPrimaryObjectId" select="/plm:TCXML/plm:IMAN_Drawing/#primary_object"/>
<xsl:variable name="RefPrimaryObjectId" select="substring($currentPrimaryObjectId,2)"/>
<xsl:call-template name="UGPart">
<xsl:with-param name="PriId" select="$RefPrimaryObjectId"/>
</xsl:call-template>
</xsl:for-each>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="/plm:TCXML/plm:UGPART" name="UGPart">
<xsl:param name="PriId"/>
<xsl:copy>
<xsl:if test="#object_name="'Test'">
<xsl:attribute name="owning_organization">
<xsl:value-of select="$PriId"/>
</xsl:attribute>
</xsl:if>
<xsl:copy-of select="#*[not(name()='owning_organization')]" />
<xsl:apply-templates />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
But the output is :
owning_organization=""
Expected Result is :
It should update owning_organization attribute which i am passing from template 1 with value = $RefPrimaryObjectId for UGPART when its #object_name="'Test'"
what is going wrong here ? why $RefPrimaryObjectId" value is not coming to second template.

You should really supply your expected output, otherwise it is really hard to understand what you want. I am making some-what of a guess as to your expected output based on your provided style-sheet.
I mean no disrespect and I am only trying to be helpful, but your style-sheet points to so many misconceptions, that rather than just picking my solution (provided below), you might be better off in the long term, by putting pens down and working through some published tutorials, or reading a book.
Any way ...
This style-sheet ...
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:plm="http://www.tcxml.org/Schemas/TCXMLSchema" >
<xsl:output method="xml" indent="yes"/>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="plm:IMAN_Drawing">
<xsl:variable name="id" select="substring(#primary_object,2)" />
<xsl:copy>
<xsl:apply-templates select="#*"/>
</xsl:copy>
<xsl:for-each select="../plm:UGPART[plm:GSIdentity/#elemId=$id]" >
<xsl:copy>
<xsl:apply-templates select="#*[name()!='owning_organization' or ../#object_name!='Test']"/>
<xsl:if test="#object_name='Test'">
<xsl:attribute name="owning_organization"><xsl:value-of select="$id" /></xsl:attribute>
</xsl:if>
<xsl:apply-templates select="node()"/>
</xsl:copy>
</xsl:for-each>
</xsl:template >
<xsl:template match="plm:UGPART" />
</xsl:stylesheet>
... when applied to your sample input, will produce output ...
<?xml version="1.0" encoding="utf-8"?>
<TCXML xmlns="http://www.tcxml.org/Schemas/TCXMLSchema">
<BOMWindow elemId="id62" revision_rule="#id60" top_line="#id2">
<GSIdentity elemId="id1" label="a00pC7EtM1CZ7D" />
</BOMWindow>
<IMAN_Drawing elemId="id78" owning_site="#id4" primary_object="#id21" secondary_object="#id25" user_data="" /><UGPART creation_date="2012-06-05T09:25:30Z" date_released="2012-06-05T09:25:33Z" ead_paragraph="" elemId="id117" format_used="PART" gov_classification="" object_name="Test" owning_organization="id21">
<GSIdentity elemId="id21" label="RXM9sPifBT4jNA" />
</UGPART>
<IMAN_Drawing elemId="id79" owning_site="#id4" primary_object="#id22" secondary_object="#id26" user_data="" /><UGPART creation_date="2012-06-05T09:25:30Z" date_released="2012-06-05T09:25:33Z" ead_paragraph="" elemId="id117" format_used="PART" gov_classification="" object_name="Test3" owning_organization="">
<GSIdentity elemId="id22" label="xuO9sPifBT4jNA" />
</UGPART>
<IMAN_Drawing elemId="id80" owning_site="#id4" primary_object="#id20" secondary_object="#id24" user_data="" /><UGPART creation_date="2012-06-05T09:25:30Z" date_released="2012-06-05T09:25:33Z" ead_paragraph="" elemId="id117" format_used="PART" gov_classification="" object_name="Test2" owning_organization="">
<GSIdentity elemId="id20" label="R3K9sPifBT4jNA" />
</UGPART>
</TCXML>
