A normal mode? Assuming you mean a resource node which are URIs. Use
librdf_node_get_uri to get the URI.
I don't see what parsing and '#' has to do with URIs. You might do that
when doing relative URI or base URI operations when serializing but in
RDF applications treat URIs as opaque. See some of the operations in
the rdf_uri.h header e.g. librdf_new_uri_relative_to_base,
librdf_new_uri_normalised_to_base
