Subject: RE: [xsl] Counting nodes From: "Andrew Welch" <awelch@xxxxxxxxxxxxxxx> Date: Tue, 2 Jul 2002 15:24:22 +0100 |
wd-xsl doesnt have a count function, so you have to write your own. This should do what you want: function count(obj,tagName) { var a = getElementsByTagName(tagName); return a.length; } Pass to it the parent element which contains all of the nodes you wish to count, and the element name. For example: <xsl:template match="lineage"> <xsl:eval>count(this,'procstep')</xsl:eval> </xsl:template> Or, the less reusable but ultimately better: <xsl:template match="lineage"> <xsl:eval>getElementsByTagName('procstep').length</xsl:eval> </xsl:template> Of course, to save your head from bursting, its easier to move to XSLT and use the count() function or <xsl:number> cheers andrew -----Original Message----- From: Mike Leahy [mailto:mgleahy@xxxxxxxxxxxxxxxx] Sent: 02 July 2002 14:52 To: XSL-List@xxxxxxxxxxxxxxxxxxxxxx Subject: [xsl] Counting nodes Hello list, I am using the namespace "http://www.w3.org/TR/WD-xsl" I would like to be able to count the occurrance of a particular tag (e.g. "procstep" can occur multiple times within "metadata/dataqual/lineage" in the XML files I am using). The count function is not a recognized function in the namespace I am using - is there any other way I could get this number?
