I'm trying to create bread-crumbing for the navigation of a website. I
have the site hierarchy in a forwards nested document like below. The
only way I could figure out how to get the bread crumbs at all was to
get a backwards result. Once I have the result doc, I dump it as a
srting to the browser. Got any ideas of a simple way to reverse the
order in xsl, or a better way to write my first xsl?
Here's how my xml document is formed.
<page>
<title>Home Page<title>
<pageid>1</pageid>
<page>
<title>Parent Page</title>
<pageid>2</pageid>
<page>
<title>This Page</title>
<pageid>3</pageid>
</page>
<page>
</page>
Here's the xslt I wrote up.
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:param name="pageid" select="23"/>
<xsl:template match="/">
<docroot>
<xsl:apply-templates mode="first"/>
</docroot>
</xsl:template>
<xsl:template match="node()" mode="first">
<xsl:apply-templates select="page" mode="first"/>
<xsl:if test="pageid=$pageid">
<xsl:call-template name="bread-crumb"/>
</xsl:if>
</xsl:template>
<xsl:template match="node()" mode="ancestor">
<xsl:call-template name="bread-crumb"/>
</xsl:template>
<xsl:template name="bread-crumb">
<xsl:text>>></xsl:text>
<xsl:element name="a">
<xsl:attribute
name="href">index.cfm?pageid=<xsl:value-of
select="pageid"/></xsl:attribute>
<xsl:value-of
select="normalize-space(pagetitle)"/>
</xsl:element>
<xsl:if test="../pageid">
<xsl:apply-templates select=".."
mode="ancestor"/>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
This is what I end up with.
<?xml version="1.0" encoding="UTF-8"?>
<docroot>
<a href="index.cfm?pageid=23">Laptop Requirements</a>
<a href="index.cfm?pageid=21">Computing</a>
<a href="index.cfm?pageid=20">Once you're admitted</a>
<a href="index.cfm?pageid=1">Admissions</a>
</docroot>
Here's the browser view.
