XSL Breakdown

As there is so much going on in the previous code I have broken it down by the key components. I have done this by working inwards by tag pair.

XSL Declaration & Stylesheet Wrapper

The first components of our xsl sheet are the xsl version namespace declarations and the desired output format of html using utf-8 encoding.

<xsl:stylesheet version="2.0" xmlns:html="http://www.w3.org/TR/REC-html40" xmlns:sitemap="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
   <xsl:output method="html" version="1.0" encoding="UTF-8" indent="yes"/>
   --snip--

   --snip--
</xsl:stylesheet>

Template Wrapper

Inside the stylesheet wrapper we have a template wrapper

<xsl:template match="/">
--snip--

--snip--
</xsl:template>

Variable Declarations

Inside the template wrapper are two variable declarations. These variables named upper and lower will be used further down the code.

    <xsl:variable name="lower" select="'abcdefghijklmnopqrstuvwxyz'"/>
    <xsl:variable name="upper" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>

Standard HTML

You will notice that there is standard html mixed in with the xsl code. This is no different to the way you have standard code mixed in with cfml.

For-Each Loop

This is where we start to see the power of xsl. This statement selects the urlset wrapper from our sitemap and loops through each url node in it.

   <xsl:for-each select="sitemap:urlset/sitemap:url">
   --snip--

   --snip--
   </xsl:for-each>
