SOAP RPC 响应解析

Question

Hi I am working on an application which is consuming SOAP RPC service. I have created a client code and getting soapmessage response from SOAP service. SOAP services are designed in old technologies and not supporting JAXB or AXIS2.

My SOAPMessage response is like:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"  xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<ns1:LoginResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1="http://DefaultNamespace">
<LoginReturn xsi:type="ns1:ResultMap">
  <items xsi:type="soapenc:Array" soapenc:arrayType="ns1:ResultMapItem[2]" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">
 <item>
  <key xsi:type="xsd:string">SOAP_SERVICE</key>
  <value xsi:type="xsd:string">https://somevalue</value>
 </item>
 <item>
  <key xsi:type="xsd:string">UI_SERVICE</key>
  <value xsi:type="xsd:string">https://somevalue</value>
 </item>
</items>
</LoginReturn>
</ns1:LoginResponse>
</soapenv:Body>
</soapenv:Envelope>

Now I have to get the value of "SOAP_SERVICE" from the map and store it into some variable. Can someone please suggest me something how I can proceed.

Thanks.

Adding the client code.

        SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
        SOAPConnection soapConnection = soapConnectionFactory.createConnection();
       String url = "https://serviceUrl"; 
       String soapRequest = "requeststring";

       System.out.println("soapRequest.."+soapRequest);

      InputStream is = new ByteArrayInputStream(soapRequest.getBytes());
      SOAPMessage request = MessageFactory.newInstance().createMessage(null, is);
      SOAPMessage soapResponse = soapConnection.call(request, url);
      ByteArrayOutputStream out = new ByteArrayOutputStream();
      soapResponse.writeTo(out);

Ok, so this might look ugly, but as you cannot use another technology, you will have to traverse the SOAP response just as a DOM object.

This means, first locate the item nodes. Then, go through them one by one, searching for the item that has a child key node with value SOAP_SERVICE .

Once found, go through key node children, until you find the value node.

Here is a working example (continued from your code)

    SOAPBody body = soapResponse.getSOAPBody();

    NodeList returnList = body.getElementsByTagName("item");

    for (int i = 0; i < returnList.getLength(); i++) {
        NodeList innerResultList = returnList.item(i).getChildNodes();

        for (int j = 0; j < innerResultList.getLength(); j++) {
            if ("KEY".equalsIgnoreCase(innerResultList.item(j).getNodeName()) 
                    && "SOAP_SERVICE".equalsIgnoreCase(innerResultList.item(j).getTextContent())) {
                for (int k = j +1; k < innerResultList.getLength(); k++){
                    if ("VALUE".equalsIgnoreCase(innerResultList.item(k).getNodeName())) {
                        System.out.println("Value for SOAP_SERVICE is " + innerResultList.item(k).getTextContent());
                        break;
                    }
                }
            }
        }
    }

Hope this helps
