I'm working with Stardog in this Java code:
Connection aConn = ConnectionConfiguration
.to("")
.server("http://localhost:5820")
.database("TP_OntologiasEjecutado")
.credentials("admin", "admin")
.connect()
.as(Connection.class);
SelectQuery selectQuery = aConn.select(
"SELECT DISTINCT ?Libreta ?Puntaje \n"+
"WHERE{ \n"+
"?Alumno a :PostulanteABecaAdmisible. \n"+
"?Alumno :cantidadMateriasAprobadasCicloLectivoAnterior ?matAnterior. \n"+
"?Alumno :promedioAlumno ?Promedio. \n"+
"?Alumno :numeroLegajo ?Libreta. \n"+
"?Alumno :medicionFinal ?Puntaje. \n"+
"?Alumno :seInscribeAConvocatoria ?conv. \n"+
"?conv :anioConvocatoria ?anioConv. \n"+
"FILTER (?anioConv = "+anio+"). \n"+
"FILTER (?Promedio >= "+promedio+"). \n"+
"FILTER (?matAnterior >= "+materias+"). \n"+
"} \n"+
"ORDER BY DESC (?Puntaje)"
);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
SelectQueryResult selectQueryResult = selectQuery.execute();
try{
QueryResultWriters.write(selectQueryResult, stream, HTMLQueryResultWriter.FORMAT);
} catch (IOException e) {
System.out.println("ERROR");
}
This generates HTML code that I show in a JLabel in a JPanel, this is an example of the code I get: HTML code and the result
And this is the opening the HTML in Notepad++:
<html>
<head><meta content="text/html;charset=UTF-8"/></head>
<body>
<table border=1>
<tr>
<th>Libreta</th>
<th>Puntaje</th>
</tr>
<tr>
<td style="text-align:left;vertical-align:top">23806</td>
<td style="text-align:left;vertical-align:top">"67.75"^^<http://www.w3.org/2001/XMLSchema#float></td>
</tr>
<tr>
<td style="text-align:left;vertical-align:top">123456</td>
<td style="text-align:left;vertical-align:top">"66.6"^^<http://www.w3.org/2001/XMLSchema#float></td>
</tr>
</table>
</body>
String finalString = new String(stream.toByteArray()).replaceAll("http://www.w3.org/2001/XMLSchema#float","");
But I can't remove the ^^<> part because they are special characters. How can I remove them?
The issue is that if you escape those characters in your regex, e.g.
you're escaping them in the string that gets created. If this even works without errors, your regex string will still be
So what you need to do is escape your backslashes, turning them into single backslashes underneath, and ensuring that they are still present when needed to escape the special regex characters:
