I have to unmarshall a XML(XML version 1) to get the values and put these ones in a new version of that XML(XML version 2). The problem is there are a lot of tags with xsi, and this fact is reflected in the unmarshalled class as abstract classes that can be extended by a various classes, and my question is, what is the way to know the class which extends of an abstract class given by the XML xsi:type? I put here my code and the resources, thanks.
XML schema that content the data that I want:
http://www.datex2.eu/content /xml-schema
XML source with data:
http://infocar.dgt.es/datex2/dgt/SituationPublication/all/content.xml
XML schema of actual version:
http://www.datex2.eu/content/datex-ii-xml-schema-23 My finall achieve is to convert the first XML in one of this.
My actually code(Testing):
public class Main {
public static void main(String[] args) throws IOException, SAXException, TransformerException, JAXBException, XMLStreamException, ParserConfigurationException {
URL url = null;
try {
url = new URL("
http://infocar.dgt.es/datex2/dgt/SituationPublication/all/content.xml");
} catch (MalformedURLException e) {
e.printStackTrace();
}
System.out.println("Abriendo URL..");
URLConnection conn = url.openConnection();
System.out.println("URL cargada");
System.out.println("Cargando los datos necesarios...");
JAXBContext jaxbContext = JAXBContext.newInstance(eu.datex.schema._1_0._1_0.D2LogicalModel.class);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
JAXBElement DatexModelElement = (JAXBElement) unmarshaller.unmarshal(url);
eu.datex.schema._1_0._1_0.D2LogicalModel datex1 = DatexModelElement.getValue();
eu.datex2.schema._2_0._2_3.D2LogicalModel datex2 = new eu.datex2.schema._2_0._2_3.D2LogicalModel();
SituationPublication situation = (SituationPublication)datex1.getPayloadPublication();
List situationList = situation.getSituation();
for (int i = 0; i < situationList.size(); ++i)
{
ListsituationRecordList = situationList.get(i).getSituationRecord();
for(int y = 0; y < situationRecordList.size(); ++y)
{
//the question is here, how to know which class extends as SituationRecord in other to have one get method or another?
}
}
}
}
