Subject: Re: [xsl] Using one nodeset to dictate the format of data from another nodeset From: "Rebecca O'Connell" <rebecca321@xxxxxxxxx> Date: Thu, 7 Jun 2007 16:54:33 -0400 |
It works perfectly. I notice it behaves the same way if I take out all of the "tunneling" parameters. What is "tunneling" supposed to do? (I thought it might make it so I could just declare my parameter in topic-ref and then use it in title without all the redundant xsl:param and xsl:with-param calls, but apparently not.)
Thanks, Rebecca
You are calling your title and content templates and passing parameters using with-param correctly (assuming you don't want to tunnel), but the title and content templates don't have an 'accepting' parameter definition, so the parameters are being discarded. The following seems to get the output you want.
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:strip-space elements="*"/>
<xsl:template match="/"> <html> <head> </head> <body> <xsl:apply-templates select="x/structure-data"/> </body> </html> </xsl:template>
<xsl:template match="topic-ref"> <xsl:param name="level" tunnel="yes" select="count(ancestor::topic-ref)+1"/> <div class="TOPIC-REF"> <xsl:apply-templates select="key('id', @idref)"> <xsl:with-param name="level" tunnel="yes" select="$level"/> </xsl:apply-templates>
<xsl:apply-templates select="topic-ref"/> </div> </xsl:template>
<xsl:template match="content"> <xsl:param name="level" tunnel="yes"/>
<xsl:apply-templates select="title" > <xsl:with-param name="level" tunnel="yes" select="$level"/> </xsl:apply-templates> </xsl:template>
<xsl:template match="title"> <xsl:param name="level" tunnel="yes"/>
<xsl:element name="{concat('h',$level)}"> <xsl:value-of select="." /> </xsl:element> </xsl:template>
<xsl:key name="id" match="content" use="@id"/> </xsl:stylesheet>
Thanks! Angela

David assumed correctly that I had one document with two parts. Your solution worked beautifully. I had a feeling that there was some simple way I was missing. I am a much happier camper (see below for the reason why I am not yet a completely happy camper).
I don't mind being corrected. I would much rather be told I'm using a term incorrectly than continue using it incorrectly.
With regard to the second part of my question (how to "feed" a template data from the template that called it), I am new to parameters (and to XSLT) and am having some difficulty figuring out how to handle them. Here's what I think I know about parameters:
1. xsl:param - used with stylesheets and templates, sets the parameter 2. xsl:with-param - used with apply-templates and call-template, changes the default value of the parameter, passes the parameter to the template being called (?) 3. xsl:value-of or select/name="{$paramName}" - used to get the value of the parameter 4. Tunnel parameters "have the property that they are automatically passed on by the called template to and further templated that it calls, and so on recursively" (as described by Oxygen).
However, clearly I don't know enough, because my attempts to use parameters are not working. Below is what I attempted:
XML: <x> <source-data> <content id="id1"><title>Title 1</title></content> <content id="id2"><title>Title 2</title></content> </source-data>
<structure-data> <topic-ref idref="id1" > <topic-ref idref="id2" /> </topic-ref> </structure-data> </x>
DESIRED OUTPUT: <html> <div><h1>Title 1</h1> <div><h2>Title 2</h2></div> </div> </html>
STYLESHEET ATTEMPT: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:strip-space elements="*"/>
<xsl:template match="/"> <html> <head> </head> <body> <xsl:apply-templates select="x/structure-data"/> </body> </html> </xsl:template>
<xsl:template match="topic-ref"> <xsl:param name="level" tunnel="yes" select="count(ancestor::*)"/> <div class="TOPIC-REF"> <xsl:apply-templates select="key('id', @idref)"> <xsl:with-param name="level" tunnel="yes" select="count(ancestor::*)"/> </xsl:apply-templates> <xsl:apply-templates select="topic-ref"/> </div> </xsl:template>
<xsl:template match="content"> <xsl:apply-templates select="title" > <xsl:with-param name="level"/> </xsl:apply-templates> </xsl:template>
<xsl:template match="title"> <xsl:element name="{concat('h',$level)}"> <xsl:value-of select="." /> </xsl:element> </xsl:template>
<xsl:key name="id" match="content" use="@id"/> </xsl:stylesheet>
What am I getting wrong here?
Thank you, Rebecca
