Question

我想在android中调用this WSDL file来检索数据。

这是RPC / Literal WSDL结构，但我无法解析它。我已经解析了基于SOAP的普通WSDL文件。

请帮我解决这个问题。

代码：

    import java.io.StringReader;

import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserFactory;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;


public class WebServiceRecetrioActivity extends Activity 
{  
    Button btnReg;
    EditText fullName,emailId,password,confirmPwd;

    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.registration_main);

        btnReg = (Button)findViewById(R.id.regId);
        fullName = (EditText)findViewById(R.id.name);
        emailId = (EditText)findViewById(R.id.emailId);
        password = (EditText)findViewById(R.id.pwd);
        confirmPwd = (EditText)findViewById(R.id.pwd1);

        btnReg.setOnClickListener(new View.OnClickListener() 
        {
            @Override
            public void onClick(View v) 
            {
                String xmlString = "http://www.danica.com.ar/recetario/recetario.wsdl"; //Added your wsdl as an xml string here

                try {
                     XmlPullParserFactory parserFactory = XmlPullParserFactory.newInstance();
                     XmlPullParser pullParser = parserFactory.newPullParser();
                     pullParser.setInput(new StringReader(xmlString));

                     int eventType = pullParser.getEventType();
                     while (true) 
                     {
                        if(eventType == XmlPullParser.START_TAG) 
                        {
                           String Tag = pullParser.getName();
                           System.out.println(Tag);

                        } 

                        else if(eventType == XmlPullParser.END_DOCUMENT)
                                break;
                        eventType = pullParser.next();
                     }
                }
                catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });


    }
}

我使用了ksoap2-android-assembly-3.1.1-jar-with-dependencies.jar

使用ksoapxml库。它有你可以使用的xml pull解析器。

String xmlString = ""; //Added your wsdl as an xml string here

try {
            XmlPullParserFactory parserFactory = XmlPullParserFactory.newInstance();
            XmlPullParser pullParser = parserFactory.newPullParser();
            pullParser.setInput(new StringReader(xmlString));

            int eventType = pullParser.getEventType();




               while (true) 
               {
                   if(eventType == XmlPullParser.START_TAG) 
                   {
                       String Tag = pullParser.getName();

                       System.out.println(Tag);

                   } 

                   else if(eventType == XmlPullParser.END_DOCUMENT)
                       break;
                   eventType = pullParser.next();
               }

HttpClient httpCLient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(serverUrl);
HttpResponse httpresponse = httpClient.execute(httpGet);
HttpEntity resEntity = httpresponse.getEntity();
String result = EntityUtils.toString(resEntity);

将结果传递给解析器。

获取每个标记的所有属性和值的列表

int count = pullParser.getAttributeCount();
for(int i=0;i<count;i++)
{
Log.d("App", pullParser.getAttributeName(i) + ":" + pullParser.getAttributeValue(i));
}

从Android调用RPC / Literal WSDL文件
