[thelist] RDF Information?

Fri Dec 13 10:47:01 CST 2002

    Okay, I can't even get a simple transformation to work!

    Here is my simple XSLT file that produces nada:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns="http://purl.org/rss/1.0/"
xmlns:dc="http://purl.org/dc/elements/1.1/">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/rdf:RDF">
<xsl:value-of select="/rdf:RDF/channel/@rdf:about"/>
</xsl:template>
<xsl:template match="*"/>
</xsl:stylesheet>

    And here's the file I'm transforming:

<?xml version="1.0"?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns="http://purl.org/rss/1.0/" xmlns:dc="http://purl.org/dc/elements/1.1/"
