java - Unmarshalled XML to abstract class, how to know the xsi:type in order to instanciate one class or another -
i have unmarshall xml(xml version 1) values , put these ones in new version of xml(xml version 2). problem there lot of tags xsi, , fact reflected in unmarshalled class abstract classes can extended various classes, , question is, way know class extends of abstract class given xml xsi:type? put here code , resources, thanks.
xml schema content data want: http://www.datex2.eu/content /xml-schema
xml source 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 finall achieve convert first xml in 1 of this.
my 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<eu.datex.schema._1_0._1_0.d2logicalmodel> datexmodelelement = (jaxbelement<eu.datex.schema._1_0._1_0.d2logicalmodel>) 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<situation> situationlist = situation.getsituation(); (int = 0; < situationlist.size(); ++i) { list<situationrecord>situationrecordlist = situationlist.get(i).getsituationrecord(); for(int y = 0; y < situationrecordlist.size(); ++y) { //the question here, how know class extends situationrecord in other have 1 method or another? } } } } situationrecord.class example:

jaxb able implement class given xml xsi automatically.
situationrecord.getclass().tostring()
the above line gives me name of class extends of situationrecord.class
