Question

I’m having some issues with incorrect XSLT transformation. My task is to convert an XML file to an RDF file using XSLT. Therefore, I’d have to create a <rdf:RDF> node with the relevant namespaces, as the root of the XML document. There are two problems in the output:

1. The exclude-result-prefixes isn’t working.
2. The formatting is horrible. For instance, the <rdf:RDF> node comes immediately after the XML declaration, and things aren’t being spaced correctly.

It does validate as RDF, though. So at least my syntax on that side is correct.

XSLT:

This is what my XSLT file looks like (other templates snipped, but I can provide full code if necessary). The only thing I can think of that could possibly be relevant is that in the templates that come afterwards I’m using <xsl:element> and <xsl:attribute> instead of directly typing in the node’s code.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
    exclude-result-prefixes="fD"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

    xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
<xsl:output method="xml" indent="yes"/>

<xsl:template match="/">

Answer 1

Had to change stuff in Eclipse’s Run settings to get it to indent correctly.
