RE: Xalan error when using xpath-default-namespace attribute

Yes, thank you keshlam. This is the solution that David Bertoni suggested (in the FAQ). It works and it is good.

Or, much better because it's semantically correct rather than looking only at syntax: bind a prefix to the namespace that code is actually in ("http://ncicb.nci.nih.gov/xml/owl/EVS/Thesaurus.owl#") and use that prefix in the XPath.

A <code> element in one namespace means something completely different from <code> in another namespace. Learn to use namespaces properly.

Ah, thank y ou Kes hlam.

In that case, let me revert to my source problem; the problem which I was hoping to solve with xsl:xpath-default-namespace attribute :-)

I have an XML (really an OWL) document which has this element at the top:

<rdf:RDF xmlns="http://ncicb.nci.nih.gov/xml/owl/EVS/Thesaurus.owl#"
xml:base="http://ncicb.nci.nih.gov/xml/owl/EVS/Thesaurus.owl#"
xmlns :prote ge="http://protege.stanford.edu/plugins/owl/protege#"
xmlns:owl="http://www.w3.org/2002/07/owl#"
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#">
Inside the document are elements like this:

<owl:Class rdf:ID="Benzo_a_pyrene-7_8-diol_9_10-Epoxide">
<rdfs:label>Benzo(a)pyrene-7,8-diol 9,10-Epoxide</rdfs:label>
<code>C196</code>
<rdfs:subClassOf rdf:resource="#DNA_Adduct_Forming_Agent"/>
<rdfs:subClassOf rdf:resource="#Intercalating_Agent"/>
........
</owl:Class>


Using Xpath inside of Xalan, I am able to access the nodes that are prefixed with a namespace (such as rdfs:subClassOf or rdf:resource). But I am unable to access the <code> element's contents because it has no namespace prefix. For example,

"owl:Class/code" does not work.

How do I formulate an Xpath _expression_ that accesses the <code> element?

Xalan is an XSLT 1.0 processor. xsl:xpath-default-namespace is not a 1.0 directive.
