[tbc-users] Re: parse xml

Thu, 16 Jul 2009 07:54:54 -0700

Catrina;  I am attaching files that run a sample XML file.  It just imports to RDF and then back to XML ans saves (the idea being that the input and output XML should be the same).

If you debug and Infer Result Triples, you will see that there is a binding for the prefix:
 <samVocab:Node> sxml:prefix samVocab

I notice that the sxml:owl contains the sxml:prefix property.  When I
imported my hierarchy, I imported using XML and ConvertXMLtoRDF.  My
input XML contains xmlns attributes on the root element.  However, I
don't see where sxml:prefix is getting set.  Do I need to set the
sxml:attribute on the sxml:prefix property?  How do I get the
namespace definitions to get stored in the RDF?

ConvertRDFtoXML will add all of the defined prefixes.  Using
smf:prefix and other SPARQL functions, you should be able to ensure
that all prefixes are defined.  Verifying XML is not part of the
Composer tool suite, so I'm not sure namespaces in XML can be
verified.

I'm not sure that even Xpath has access to namespace prefixes in XML
files (http://composing-the-semantic-web.blogspot.com/2009/05/
interacting-with-xml-based-web-services.html).

How does that put the namespace prefix definitions in the XML?
      
For example, my XML needs to contain:
<skos:Concept xmlns:skos="http://www.w3.org/2004/02/skos/core"
      
I want to parse the XML, to ensure that all needed namespace
definitions exist in the XML.
