xml解析+ Java ME

如何解决xml解析+ Java ME

| 我正在编辑我的问题，以清楚地了解字符串名称resfile_name和结果 我想进行xml解析。在这里我将一些参数传递给url ane，它以xml格式给我响应，我以字符串名称结果将其接收，现在我想解析该字符串（xml数据）。 我正在使用以下代码：-

     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,\"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;
    }

Constants.callSoap（\“ GetChildList \”，vector）;在具有代码的常量中调用callsoap方法：

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; }; }

实际的响应是这样的：                                                  452                本地                958694                自由                2011-05-26T16：22：21.29                1个                1个                                          502                测试                123456                                                0                1个                                          523                abc                124124                                                0                1个                                       

解决方法

以下代码将在类路径中使用传入参数的名称查找资源，并且您正在传递整个XML，因此NPE很明显。

this.getClass().getResourceAsStream(resfile_name)

最好从URL获取inputStream，如下面的虚线所示，然后继续

 HttpConnection hc = null;

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