解组与复杂类型

Question

我无法解组代表此格式的发票的XML：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <soap:Body>
        <Response xmlns="Lamp">
            <Result>
                <Title>The Title</Title>
                <Lines>
                    <anyType xsi:type="InvoiceLine">
                        <Name>Name One</Name>
                        <Quantity>1.0000</Quantity>
                    </anyType>
                    <anyType xsi:type="InvoiceLine">
                        <Name>Name Two</Name>
                        <Quantity>2.0000</Quantity>
                    </anyType>
                </Lines>
            </Result>
        </Response>
    </soap:Body>
</soap:Envelope>

发票类：

@XmlAccessorType(XmlAccessType.FIELD)
public class Invoice {
    public String Title;
    public List<InvoiceLine> Lines;
}

InvoiceLine类：

@XmlAccessorType(XmlAccessType.FIELD)
public class InvoiceLine extends anyType {
    public String Name;
    public float quantity;
}

anyType的抽象类：

public abstract class anyType {}

这是我用来进行解组的代码：

public static void main(String[] args) throws Exception {

    InputStream is = new FileInputStream("input.xml");

    XMLInputFactory xif = XMLInputFactory.newFactory();
    XMLStreamReader xsr = xif.createXMLStreamReader(is);

    xsr.nextTag();
    while(!xsr.getLocalName().equals("Result")) {
        xsr.nextTag();
    }

    JAXBContext jc = JAXBContext.newInstance(Invoice.class, InvoiceLine.class);
    javax.xml.bind.Unmarshaller unmarshaller = jc.createUnmarshaller();

    JAXBElement<Invoice> jb = unmarshaller.unmarshal(xsr, Invoice.class);
    xsr.close();

    System.out.println(jb.getValue());

}

问题是，Lines列表只包含1个Name = null和quantity = 0.0的条目。

- 编辑：

我刚尝试将XmlElement和XmlElementWrapper注释添加到这两个类中，唯一的变化是Lines列表没有元素。

修改发票：

@XmlAccessorType(XmlAccessType.FIELD)
public class Invoice {
    @XmlElement(name = "Title")
    public String Title;
    @XmlElement(name = "anyType")
    @XmlElementWrapper(name = "Lines")
    public List<InvoiceLine> Lines;
 }

修改后的InvoiceLine：

@XmlAccessorType(XmlAccessType.FIELD)
public class InvoiceLine extends anyType {
    @XmlElement(name = "Name")
    public String Name;
    @XmlElement(name = "Quantity")
    public float Quantity;
}

- 编辑： 我只是尝试将属性设置为小写，但仍然没有运气。
