This solution uses Sesame-Rio to parse the RDF into single Statements.

gistfile1.java

private void loadRdfXml(InputStream is, UID context) {
	try {
		
		UID currentContext = context != null ? context : defaultGraph;
		
		RDFParser rioParser = Rio.createParser(RDFFormat.RDFXML);
		StatementCollector handler = new StatementCollector();
		rioParser.setRDFHandler(handler);
		rioParser.parse(is, currentContext.getId());
		
		SesameDialect dialect = new SesameDialect(ValueFactoryImpl.getInstance());
		Collection<STMT> stmts = new ArrayList<STMT>();
		
		for(org.openrdf.model.Statement s : handler.getStatements()) {
			ID subject = dialect.getID(s.getSubject());
			UID predicate = dialect.getUID(s.getPredicate());
			NODE object = dialect.getNODE(s.getObject());
			
			stmts.add(new STMT(subject, predicate, object, currentContext));
			
			if(stmts.size() > 5000) {
				update(null, stmts);
				stmts.clear();
			}
		}
		
		update(null, stmts);
