xml解析+ Java ME

Question

我正在编辑我的问题，以清楚地了解有关字符串名称resfile_name和结果 我想要做xml parsing.where我传递一些参数到url ane它使我以xml格式响应我现在我想要解析该字符串（xml数据）。 我使用的follwing以下代码： -

 SAXParserFactory factory = SAXParserFactory.newInstance(); 
      SAXParser saxParser = factory.newSAXParser(); 
      vector = new Vector(); 
      vector.addElement(new KeyPair("ParentID", "10000186")); 
      String result = Constants.callSoap("GetChildList", vector); 
      InputStream is = new ByteArrayInputStream(result.getBytes("UTF-8")); 
Reader reader = new InputStreamReader(in); 
    XmlParser parser = new XmlParser(reader); 
    ParseEvent pe = null; 
    Reader reader = new InputStreamReader(in); 
    XmlParser parser = new XmlParser(reader); 
    ParseEvent pe = null; 
    parser.skip(); 
    parser.read(Xml.START_TAG, null, "GetChildListResult"); 
    parser.skip(); 
    parser.read(Xml.START_TAG, null, "CustomChildList"); 

    boolean trucking = true; 
    boolean first = true; 
    while (trucking) { 
     pe = parser.read(); 
     if (pe.getType() == Xml.START_TAG) { 
     String name = pe.getName(); 
      System.out.println("nAME=="+name); 
     if (name.equals("ChildID")) { 
      String title, link, description; 
      title = link = description = null; 
      while ((pe.getType() != Xml.END_TAG) || 
       (pe.getName().equals(name) == false)) { 
      pe = parser.read(); 
      if (pe.getType() == Xml.START_TAG && 
       pe.getName().equals("ChildName")) { 
       pe = parser.read(); 
       title = pe.getText(); 
      } 
      else if (pe.getType() == Xml.START_TAG && 
       pe.getName().equals("IMEINumber")) { 
       pe = parser.read(); 
       link = pe.getText(); 
      } 
      else if (pe.getType() == Xml.START_TAG && 
       pe.getName().equals("ChildStatus")) { 
       pe = parser.read(); 
       description = pe.getText(); 
      } 
      } 

     } 
     else { 
      while ((pe.getType() != Xml.END_TAG) || 
       (pe.getName().equals(name) == false)) 
      pe = parser.read(); 
     } 
     } 
     if (pe.getType() == Xml.END_TAG && 
      pe.getName().equals("GetChildListResult")) 
     trucking = false; 
    } 

的Constants.callSoap（ “GetChildList”，向量）;调用callsoap方法中的常数具有代码： -

public static String callSoap(String method, Vector vector) { 
     String result = null; 
     Constants.log("callSoap"); 
     try { 
      SoapObject request = new SoapObject(NAMESPACE, method); 
      if (vector != null) { 
       for (int i = 0; i < vector.size(); i++) { 
        KeyPair keyPair = (KeyPair) vector.elementAt(i); 
        request.addProperty(keyPair.getKey(), keyPair.getValue()); 
       } 
      } 
      Constants.log("callSoap2"); 
      Element[] header = new Element[1]; 
      header[0] = new Element().createElement(NAMESPACE, "AuthSoapHd"); 
      Element username = new Element().createElement(NAMESPACE, "strUserName"); 
      username.addChild(Node.TEXT, "*****"); 
      header[0].addChild(Node.ELEMENT, username); 
      Element password = new Element().createElement(NAMESPACE, "strPassword"); 
      password.addChild(Node.TEXT, "******"); 
      header[0].addChild(Node.ELEMENT, password); 
      SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
      envelope.dotNet = true; 
      envelope.headerOut = header; 
      envelope.setOutputSoapObject(request); 
      Constants.log("callSoap3");   
    HttpTransport transport = new HttpTransport("http://***.***.*.***/ChildTrackerService/ChildTrackerService.asmx?wsdl"); 
      //log("Log:transport"); 
      transport.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"UTF-8\"?>"); 
      //log("Log:transport1"); 
      try { 
       transport.call("http://tempuri.org/" + method, envelope); 
       //log("Log:transport:call");     
       result = (envelope.getResponse()).toString(); 


      } catch (Exception e) { 
       System.out.println("exception of IP==" + e); 
      } 
     } catch (Exception e) { 
      log("Exception CallSoap:" + e.toString()); 
     } 
     return result; 
    } 

And the class keypair contain:- 

public KeyPair(String key, String value) { 
     this.key = key; 
     this.value = value; 
    } 



    public String getKey() { 
     return key; 
    } 

    public String getValue() { 
     return value; 
    } 




The string reult has -- 
result==anyType{CustomChildList=anyType{ChildID=452; ChildName=Local; IMEINumber=958694; ChildStatus=Free; ExpiryDate=2011-05-26T16:22:21.29; RemainigDays=1; SOS=1; }; CustomChildList=anyType{ChildID=502; ChildName=testing; IMEINumber=123456; ChildStatus=anyType{}; ExpiryDate=null; RemainigDays=0; SOS=1; }; CustomChildList=anyType{ChildID=523; ChildName=abc; IMEINumber=124124; ChildStatus=anyType{}; ExpiryDate=null; RemainigDays=0; SOS=1; }; } 

实际的反应是这样的： -

下面的代码将寻找资源类路径中的参数传递的名称和要传递整个XML，所以NPE是显而易见的。

this.getClass().getResourceAsStream(resfile_name) 

你最好从URL InputStream中，如下图所示碎段，然后继续前进

HttpConnection hc = null; 

     try { 
      hc = (HttpConnection)Connector.open(url); 
      parse(hc.openInputStream());
