如何使用apache骆驼从肥皂反应中获得价值？

我想从下面的肥皂响应中获取AddResult的值，即100：

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><AddResponse xmlns="http://tempuri.org/"><AddResult>100</AddResult></AddResponse></soap:Body></soap:Envelope>

以下是Java代码：

package com.learncamel.routes.xmlxstream;

import java.util.HashMap;
import java.util.Map;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.dataformat.xstream.XStreamDataFormat;

import com.learncamel.domain.AddResponse;

public class XmlResponseToObject extends RouteBuilder{

    @Override
    public void configure() throws Exception {
        // TODO Auto-generated method stub
        Map<String, String> reference = new HashMap<String, String>();
        reference.put("AddResponse ", AddResponse.class.getName());

        XStreamDataFormat xstreamDataFormat = new XStreamDataFormat();
        xstreamDataFormat.setAliases(reference);
        xstreamDataFormat.setPermissions(AddResponse.class.getName());

        try { 
            from("direct:xmlinput")
            .log("Received Message before unmarshal is ${body} and Headers are ${headers}")
            .unmarshal(xstreamDataFormat)
            .log("Received Message after unmarshal is ${body} and Headers are ${headers}")
            .to("log:?level=INFO&showBody=true");
       } catch(Exception e) {
            e.printStackTrace();
       }       
    }
}

下面是junit代码：

package com.learncamel.routes.xmlxstream;

import org.apache.camel.RoutesBuilder;
import org.apache.camel.test.junit4.CamelTestSupport;
import org.junit.Test;

public class XmlResponseToObjectTest extends CamelTestSupport {

    @Override
    public RoutesBuilder createRouteBuilder() throws Exception {
        return new XmlResponseToObject();       
    }   

    @Test
    public void unMarshalTest() throws InterruptedException{
        //AddResponse addresponse=new AddResponse();
        String input="<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"><soap:Body><AddResponse xmlns=\"http://tempuri.org/\"><AddResult>100</AddResult></AddResponse></soap:Body></soap:Envelope>";
        template.sendBody("direct:xmlinput",input);
    }
}

以下是POJO：

package com.learncamel.domain;



public class AddResponse {

    private String AddResult;

    public String getAddResult() {
        return AddResult;
    }

    public void setAddResult(String addResult) {
        AddResult = addResult;
    }
}
