It's almost that. In XPath you have to use div instead of /:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:output indent="yes"/>
    <xsl:template match="emp">
        <result>
            <xsl:value-of select="emp_sal * emp_sal1 div emp_total"/>
        </result>
    </xsl:template>
</xsl:stylesheet>

This produces:

<result>200000</result>

The template maches a node in the source document (<emp>), which creates the context for the node names used in the XPath expression (emp_sal, emp_sal1 and emp_total) in the xs:value-of select.
