Sorry, RDF is serialized into XML in such a way that the URI occurs  
in full:

     <con:Male rdf:about="http://www.w3.org/People/Berners-Lee/card#i">
         <rdf:type rdf:resource="http://xmlns.com/foaf/0.1/Person"/>
         <s:label>Tim Berners-Lee</s:label>
         <con:assistant rdf:resource="http://www.w3.org/People/ 
Berners-Lee/card#amy"/>
	   ...

etc in the RDF/XML version (which you can access specifically as  
<http://www.w3.org/People/Berners-Lee/card.rdf>)
The RDF/XML spec describes how to parse an RDF/XML document.  It does  
not involve looking for attribute name "i".

The N3 notation <http://www.w3.org/People/Berners-Lee/card.n3>), that  
is hand edited, and that is the source from which the .rdf is  
generated, may be easier to read, though it is not designed at all as  
a tutorial.
