SPARQL query

Hello,
i have a few quetions.
First i have this prefix in the query
String queryRequest =
"PREFIX base: <"+namespace+"> " +
"PREFIX rdf:<http://www.w3.org/1999/02/22-rdf-syntax-ns#> \n" +
"PREFIX rdfs:<http://www.w3.org/2000/01/rdf-schema#> \n" +
"PREFIX xsd:<http://www.w3.org/2001/XMLSchema#> \n" +
and when i execute the query ,i got this results.
aaa^^http://www.w3.org/2001/XMLSchema#string.
bbb^^http://www.w3.org/2001/XMLSchema#string.
But i need to remove this part (http://www.w3.org/2001/XMLSchema#string)
when displaying the results. How can i do this?
Second, i put my result in a text area,
String [] res={"","",""};
res=Outils.chercher(s,d);
jTextArea1.append(res[0]);
System.out.println(res[0]);
......
RDFNode name1 = soln.get("ex");
res[0]=res[0]+name1.toString()+"\n";
return res;
But it's not nice and i want to put in in a table,how can i do this?
My last quetions : it's possible to use HTML with netbeans for displaying
query result in order to have a moere beautiful view?
Thans very much
