I'm trying to parse xml from this url

http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quote%20where%20symbol%20in%20(%22MSFT%22)&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys

and while using the methods getName() and all it gives the null value. Below is the code that is in thread, could you please tell me where the error is.

             @Override
    protected String doInBackground(String... arg0) {
        // TODO Auto-generated method stub
        String urlString = arg0[0];
        String text = null;
        InputStream is = null;
        //String tagName = null;
        int count = 0;
        try {

            URL url = new URL(urlString);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection(); 
            connection.setReadTimeout(10*1000);
            connection.setConnectTimeout(10*1000);
            connection.setRequestMethod("GET");
            connection.setDoInput(true);
            connection.connect();

            int response = connection.getResponseCode();
            Log.d("debug", "the response is"+response);
            is =  new BufferedInputStream(connection.getInputStream());

            XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
            factory.setNamespaceAware(true);

            XmlPullParser xpp = factory.newPullParser();
            xpp.setInput(is, null);

            int eventType = xpp.getEventType();
            Log.d("kchayar", is+"");
            while(eventType != XmlPullParser.END_DOCUMENT){

            String  tagName = xpp.getName();


                    if( eventType == XmlPullParser.START_TAG ){
                    //  if( tagName.equals("Change")){
                        //  text = xpp.nextText();
                        count ++;


                    //  }
                    }
                    if( eventType == XmlPullParser.TEXT ){
                    //  if( tagName.equals("Change")){
                            text = xpp.nextText();
                        count ++;


                        //}
                    }


                eventType = xpp.next(); 


            }




        } catch (XmlPullParserException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return null; 

    }

    @Override
    protected void onPostExecute(String result) {
        // TODO Auto-generated method stub
        super.onPostExecute(result);
        wv.setText(result);
    }



}

Answer 1

String  tagName = xpp.getName();

I think this line shouldn't be inside

if(eventType==XmlPullParser.START_TAG)
