Hi! Try this one: <xsl:template name="SearchNext"> <xsl:param name="letter"/> <xsl:param name="nodes" select="/beers/beer[starts-with(@name,$letter)]"/> <xsl:choose> <xsl:when test="count($nodes)>0"> <xsl:value-of select="$nodes[1]/@name"/> </xsl:when> <xsl:when test="substring(/beers/beer[position()=last()]/@name,1,1)>substring($alph abet,string-length($alphabet),1)"> <xsl:value-of select="/beers/beer[1]/@name"/> </xsl:when> <xsl:otherwise> <xsl:call-template name="SearchNext"> <xsl:with-param name="letter" select="substring(substring-after($alphabet,$letter),1,1)"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:template> it worked with the xml you provide.

Mulberrytech. Com Subject: XSLT to find missing characters? Was hoping for a few hundred extra pairs of eyes for this, maybe another solution. I need to find the first element in a node set that matches a criteria. If that node is not present in the node set, grab the next node in the node set alphabetically. Here's the example: <beers> <beer name="Amstel Light"/> <beer name="Budweiser"/> <beer name="Bud Lite"/> <beer name="Coors"/> <beer name="Michelob"/> <beer name="Miller Lite"/> <beer name="Sam Adams"/> </beers> If "B" is sent as the parameter, "Budweiser" is output. If "D" is sent, then "Michelob" is output. If no matches are found, the first element is used for the output. Here is my working stylesheet. I was wondering if anyone could think of a different approach to solving this problem, perhaps with fewer string manipulations? <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:param name="searchLetter" select="'D'"/> <xsl:variable name="alphabet" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/> <xsl:output method="text"/> <xsl:template match="/"> <xsl:variable name="beerName"> <xsl:call-template name="CheckAlphabet"> <xsl:with-param name="charPos" select="string-length(substring-before($alphabet,$searchLetter)) + 1"/> </xsl:call-template> </xsl:variable> <xsl:value-of select="$beerName"/> </xsl:template> <xsl:template name="CheckAlphabet"> <xsl:param name="charPos" select="1" /> <xsl:variable name="alphabetLength" select="26" /> <xsl:choose> <xsl:when test="$charPos <= $alphabetLength"> <xsl:choose> <xsl:when test="/beers/beer[starts-with(@name,substring($alphabet,$charPos,1))][1]"> <xsl:value-of select="/beers/beer[starts-with(@name,substring($alphabet,$charPos,1))][1]/@ name"/> </xsl:when> <xsl:otherwise> <xsl:call-template name="CheckAlphabet"> <xsl:with-param name="charPos" select="$charPos + 1"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:when> <xsl:otherwise> <xsl:value-of select="/beers/beer[1]/@name"/> </xsl:otherwise> </xsl:choose> </xsl:template> </xsl:stylesheet> Kirk Allen Evans http://www.xmlandasp.net "XML and ASP.NET", New Riders Publishing http://www.amazon.com/exec/obidos/ASIN/073571200X XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
