Question

How to parse xml having parent node name as string in jaxb. I am trying to parse my xml string by binding into a model class using JAXB. My xml string looks something like this:

String inputXml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
            + "<string xmlns=\"http://tempuri.org/\">\n"
            + " <Response Code=\"1212\">\n"
            + "     <Message>Operation is succesfully completed</Message>\n"
            + " </Response>\n"
            + "</string>";

My question is how can I create a model class to map this xml into it? If I remove the string parent node like this:

String inputXml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
            + " <Response Code=\"1212\">\n"
            + "     <Message>Operation is succesfully completed</Message>\n"
            + " </Response>\n";

I can create a model class as:

@XmlRootElement(name = "Response")
public class Response {

String Code;
String Message;
public String getCode() {
    return Code;
}

@XmlAttribute(name = "Code")
public void setCode(String Code) {
    this.Code= Code;
}

public String getMessage() {
    return Message;
}

@XmlElement(name = "Message")
public void setMessage(String Message) {
    this.Message = Message;
}    

@Override
public String toString() {
    return Message;
}
}

And in my java class I can parse using JAXB as:

    InputSource inputSource = new InputSource(new StringReader(inputXml));

    // map xml to model class in jaxb
    JAXBContext jaxbContext = JAXBContext.newInstance(Response.class);
    Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
    Response response = (Response) jaxbUnmarshaller.unmarshal(inputSource);

But I have to parse with xml that have

< string xmlns=\\" http://tempuri.org/ \\">...< /string>

as parent node. I even tried to follow this answer: How to parse/unmarshall the string xml inside a string xml into a Java object?

but not working. Am I missing something?

You need to wrap the content in a StringReader,

StringReader reader = new StringReader(inputXml);
JAXBContext jaxbContext = JAXBContext.newInstance(Response.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
Response response = (Response) jaxbUnmarshaller.unmarshal(reader);
