Subject: Re: [xsl] looping problem, <xsl: for-each>?? From: Wendell Piez <wapiez@xxxxxxxxxxxxxxxx> Date: Thu, 09 Oct 2003 16:36:41 -0400 |
I applied your suggestion to store an intermediate tree fragment in a variable, and then converting the variable into a nodeset. By iterating the nodeset, I am able to generate numbers 1,2,3,4..
The XSL is --
<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xalan="http://xml.apache.org/xalan"> <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:key name="x" match="/rss/channel/item"
use="category"/>
<xsl:template match="/">
<xsl:variable name="treeFrag">
<rootelem>
<xsl:for-each select="rss/channel/item">
<xsl:if test="generate-id(.) = generate-id(key('x',
category)[1])">
<h1> <xsl:value-of select="category"/>
</h1>
<xsl:for-each select="key('x', category)">
<desc>
<xsl:value-of select="description"/>
</desc>
</xsl:for-each>
</xsl:if>
</xsl:for-each>
</rootelem>
</xsl:variable>
<xsl:for-each select="xalan:nodeset($treeFrag)/rootelem/desc"> <xsl:if test="name(preceding-sibling::*[1]) = 'h1'"> <h1> <xsl:value-of select="preceding-sibling::*[1]" /> </h1> </xsl:if> ITEM<xsl:value-of select="position()"/> <xsl:value-of select="."/> </xsl:for-each> </xsl:template>
</xsl:stylesheet>
In the above solution, though numbers are getting generated properly, but to output <h1> tags at the right place, I had to write a slightly complex syntax * xsl:if test="name(preceding-sibling::*[1]) = 'h1'" *
<xsl:apply-templates select="xalan:nodeset($treeFrag)/rootelem" mode="treefrag"> </xsl:for-each> </xsl:template>
<xsl:template match="h1" mode="treefrag"> <xsl:copy-of select="."/> </xsl:template>
Cheers, Wendell
