Worse than a newbie question - a question that was only asked 24 hours ago... Mike Kay's response: "Your first job is to tokenize this. Some processors (and EXSLT) have an xx:tokenize() extension function that makes this easy; the only other way is to use a recursive template (which isn't very difficult). Let's say you end up with a variable $colours containing a node-set in which there are four elements whose string values are blue, red, etc," My response: If you aren't using a processor which supports tokenize() then use the recursive method: --------------------- <xsl:variable name="t"> <xsl:call-template name="getTotal"> <xsl:with-param name="s" select="normalize-space(ITEM/@cols)"/> <xsl:with-param name="x" select="'1'"/> </xsl:call-template> </xsl:variable> <xsl:template name="getTotal"> <xsl:param name="s"/> <xsl:param name="x"/> <xsl:choose> <xsl:when test="contains($s, ',')"> <xsl:call-template name="getTotal"> <xsl:with-param name="s" select="substring-after($s,''')"/> <xsl:with-param name="x" select="$x + 1"/> </xsl:call-template> </xsl:when> <xsl:otherwise><xsl:value-of select="$x"/></xsl:otherwise> </xsl:choose> </xsl:template> --------------------- Then the total number of items in the cols attribute will be given by: <xsl:value-of select="$t" /> Rgs, Ben Robb -----Original Message----- From: john liao [mailto:jliao2k@xxxxxxxxx] Sent: 02 October 2002 17:36 To: XSL-List@xxxxxxxxxxxxxxxxxxxxxx Subject: [xsl] counting the number of tokens in a string? Hi, another newbie question. Is there an easy way to count the number of commas in a string? Like this: <ITEM cols="col1,col2,col3,col4"/> I would like to print 4 for the number of columns in my ITEM. I searched on tokenize() but most of the references are about the existence of it.
