    max() value?

    XSLT

    I have x number of nodeid's stored in a cookie. I want to loop through these nodeid's and find the nodeid containing the highest (max()) value for a certain field in the node - any suggestion on a approach of finding the max/highest value?

    Hi Dinovo

    I think you should be able to do that by writing a loop like this

    <xsl:for-each select="yourexpression">
    <xsl:sort select="yourvalue" order="descending" data-type="number" />
    <xsl:if test="position() = 1>

    <xsl:value-of select="." />

    </xsl:if>
    </xsl:for-each>

    Hope this helps

    /Jan

    Hi Jan

    That is excatly the way i have done it uptil now - but i was wondering if there was no easier way of doing it (ie. lesser code)? ;-)

    Hello again

    I'm not sure it can be done using "pure" XSLT - but maybe you can use some of the extensions from the Exslt.ExsltMath library? There is a "highest" and "max" function in there it seems.
