需要在 opengts 中获取值

Question

<?xml version='1.0' encoding='UTF-8' standalone='no' ?>
<GTSResponse command="dbget" result="success">
<Record table="Device" partial="true">
    <Field name="accountID" primaryKey="true"><![CDATA[UsRentcar]]></Field>
    <Field name="deviceID" primaryKey="true"><![CDATA[85412452145214]]></Field>
    <Field name="lastOdometerKM">12222.0442925558</Field>
    <Field name="description"><![CDATA[Toyota Land Cruser]]></Field>
</Record>
<Record table="Device" partial="true">
    <Field name="accountID" primaryKey="true"><![CDATA[UsRentcar]]></Field>
    <Field name="deviceID" primaryKey="true"><![CDATA[843254752364]]></Field>
    <Field name="lastOdometerKM">4348.48814289997</Field>
    <Field name="description"><![CDATA[Chevrolet white]]></Field>
</Record>   

我在上面还有另一个带有各种记录的响应节目。如何在每条记录中将两个字段值放在一起。例如：

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

我该怎么做？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 来实现此目的：

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()));
}

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