Re: [xsl] XSL rule for sorting the elements in descending order and display ing the first element in sorted list

i.e. to output the maximum of the list.

To sort you need the xsl:sort element.  The xsl:sort element has to go
within something that iterates over a node set, such as an
xsl:for-each.

To select the first item, you need an xsl:if.  You can test the
position() of the item in the node list.  If it's equal to 1 then it's
the first item.

Putting that together, you get:

<xsl:template match="JartaXmlReport">
   <xsl:for-each select="SessionStartupTime">
      <xsl:sort data-type="number" order="descending" />
      <xsl:if test="position() = 1">
         <xsl:value-of select="." />
      </xsl:if>
   </xs:for-each>
</xsl:template>

I hope that helps,

Jeni
