Show stack trace in NUnit report in CruiseControl Dashboard

In order to have stack train in CruiseControl NUnit webdashboard report, I have added <xsl:value-of select="./failure/stack-trace"/> in webdashboard\xsl\nunitv2.xsl file. Here is the snippet

        <xsl:if test="@success != 'True' ">
      <tr bgcolor="#FF9900"><td colspan="3"><xsl:value-of select="./failure/message"/><br></br><br></br><xsl:value-of select="./failure/stack-trace"/></td></tr>
</xsl:if>
