我上面有另一个回复节目，上面有各种记录。如何在每条记录中放置两个字段值。例如：

String [] ListDevice_&_ListDescripcion = { 85412452145214 , Toyota Land Cruser ; 843254752364, Chevrolet white ;....} ;

我该怎么办？这是我的结果。请帮忙！

name="accountID" UsRentcar
name="deviceID" 85412452145214 ; name="lastOdometerKM" 14214.0020055 ; name="description" Toyota Land Cruser ; name="accountID" UsRentcar ; name="deviceID" 843254752364; name="lastOdometerKM" 4348.488142847 
name="description" Chevrolet white –

您可以使用JAXB：

创建表示XML的类：

@XmlRootElement(name = "GTSResponse")
@XmlAccessorType(XmlAccessType.FIELD)
public static class GTSResponse {

    @XmlElement(name = "Record")
    List<Record> records;
}

@XmlRootElement(name = "Record")
@XmlAccessorType(XmlAccessType.FIELD)
public static class Record {

    @XmlElement(name = "Field")
    List<Field> fields;

}

@XmlRootElement(name = "Field")
@XmlAccessorType(XmlAccessType.FIELD)
public static class Field {

    @XmlAttribute(name = "name")
    String name;
    @XmlAttribute(name = "primaryKey")
    boolean primaryKey;

    @XmlValue
    String data;
}

并像这样使用：

@Test
public void testName() throws Exception {
    String f = ...; // path to XML

    JAXBContext context = JAXBContext.newInstance(GTSResponse.class);
    Unmarshaller unma = context.createUnmarshaller();
    // here you can pass a inputStream instead of a new File
    GTSResponse response = (GTSResponse) unma.unmarshal(new File(f));

    List<String> result = new ArrayList<String>();
    for (Record r : response.records) {
        System.out.println("Start record");
        for (Field fi : r.fields) {
            System.out.println(fi.name + ":" + fi.data + "(Primary: "
                    + fi.primaryKey + ")");
            if (fi.name.equals("deviceID") || fi.name.equals("description"))
                result.add(fi.data);
        }
    }

    // The array this print is exactly as you want
    System.out.println(Arrays.toString(result.toArray()));

}

注意，您可以使用JAXB将XML映射到具有XPATH的类，注释为@XMLPath，注释是MOXY的一部分。

需要在opengts中获取值
