Hi Stuart, > My xsl doc contains a variable holding the Request URI.

Your definition of "closest matching" seems to be "the longest url that matches the start of RequestURI". Assuming the request URI is held in a variable called $RequestURI, you can get this by selecting the <domain> elements where $RequestURI starts with the value of their <url> child, sorting them in descending order by the string length of the url, selecting the first one, and getting its <controller>: <xsl:for-each select="/root/domain[starts-with($RequestURI, url)]"> <xsl:sort select="string-length(url)" data-type="number" order="descending" /> <xsl:if test="position() = 1"> <xsl:value-of select="controller" /> </xsl:if> </xsl:for-each> Cheers, Jeni --- Jeni Tennison http://www.jenitennison.com/
