Are you looking something like this:-

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:msxsl="urn:schemas-microsoft-com:xslt"
                version="1.0">
    <xsl:variable name="Session">
    <Store>
            <Name>myname</name>
            <ContactId>1234</ContactId>
    </Store>
    </xsl:variable>

    <xsl:template match="/">
       <xsl:value-of select="msxsl:node-set($Session)/Store/ContactId/text()">
    </xsl:template>
</xsl:stylesheet>
