我必须解组XML（XML版本1）以获取值并将这些值放入该XML的新版本（XML版本2）中。问题是xsi有很多标签，这个事实在unmarshalled类中反映为可以通过各种类扩展的抽象类，我的问题是，知道扩展的类的方法是什么？ XML xsi：type给出的抽象类？我把我的代码和资源放在这里，谢谢。
内容我想要的数据的XML架构： http://www.datex2.eu/content /xml-schema
包含数据的XML源： http://infocar.dgt.es/datex2/dgt/SituationPublication/all/content.xml
实际版本的XML架构： http://www.datex2.eu/content/datex-ii-xml-schema-23我的finall实现是转换其中一个XML。
我的实际代码（测试）：
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();
for (int i = 0; i < situationList.size(); ++i)
{
List<SituationRecord>situationRecordList = 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?
}
}
}
}
