Hey, I'm building an ontology in Protégé and I want to transform parts of it (e.g. the instances) to HTML with XSL. When I was transforming another file with 'simple' XML-tags like <author> before, I got it working, but the OWL-file is formatted differently and I don't know how to access the elements. I'll post the .owl file below, but this is basically what I want to get from the file (the course name):

Code: 
<Course rdf:ID="AdvancedKnowledgeTechnology">
    <CourseName rdf:datatype="[URL unfurl="true"]http://www.w3.org/2001/XMLSchema#string"[/URL]
    >Advanced Knowledge Technology</CourseName>
...
</Course>

Any kind of help is appreciated.

The OWL-file:

Code: 
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="MasterAI.xsl"?>

Just include the namespaces at the top of the XSL file:
Code: 
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="[URL unfurl="true"]http://www.w3.org/1999/XSL/Transform"[/URL] xmlns:rdf="[URL unfurl="true"]http://www.w3.org/1999/02/22-rdf-syntax-ns#"[/URL] xmlns:rdfs="[URL unfurl="true"]http://www.w3.org/2000/01/rdf-schema#"[/URL] xmlns:owl="[URL unfurl="true"]http://www.w3.org/2002/07/owl#"[/URL] xmlns="[URL unfurl="true"]http://www.owl-ontologies.com/unnamed.owl#"[/URL] xml:base="[URL unfurl="true"]http://www.owl-ontologies.com/unnamed.owl">[/URL]
Then refer to the nodes as rdf:mynode/owl:mynode/........

You'll probably hit a problem because you're using a default namespace. See FAQ for help with that.

Yes, thank you, the default namespace was the problem. Now it works. :)
