How do I use xmlpullparser

Hi there,

I am trying all day long to get a grasp about XmlPullParser. I just have to parse files like:

<?xml version="1.0" encoding="utf-8"?>
<NResultAuthorize xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><WebServiceUrl>http://xxx.xxx.com/rest/xxxx-1.0.php</WebServiceUrl><Success>true</Success></NResultAuthorize>

And I simply don't find a way to get the value "true" out of this string. Any code snipped would be very appreciated...

Hi,

I stripped it down to the below...

Button go = (Button) findViewById(R.id.do_action);
        go.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                           try {
                            URL text = new URL("http://xx.xx.xx.210/REST/Service.php?method=XMLAuthorize&username=john&password=pass&type=XML");
                           
                           
                            XmlPullParserFactory parserCreator = XmlPullParserFactory.newInstance();
                            XmlPullParser parser = parserCreator.newPullParser();

                            parser.setInput(text.openStream(), null);

                         
                           
                            int eventType = parser.getEventType();
                           
                            while (eventType != XmlPullParser.END_DOCUMENT) {
                            if (eventType ==XmlResourceParser.TEXT){
                                  Log.d("", "Document Start");
                                  String strName = parser.getName();
                                  if (strName.equals("Success")){
                                        Log.d("","Found SUCCESS tag");
                                        Log.d("","The authvalue SUCCESS is"+parser.getAttributeValue(null, "Success"));
                                        
                                        
                                  }
                            }
                               
                                                };

                                     
                               

                                eventType = parser.next();
                                Log.d("","Did not find it");
                           
                           

                        } catch (Exception e) {
                            Log.e("Net", "Error in network call", e);
                        }
            }
});}
}

I am not able to test this code properly, but give it a try and see what you get. There may still be some errors in it but it will hopefully put you on the right track.

public void onClick(View v)
    {
        try
        {
            URL text = new URL("http://xx.xx.xx.210/REST/Service.php?method=XMLAuthorize&username=john&password=pass&type=XML");
            
            
            XmlPullParserFactory parserCreator = XmlPullParserFactory.newInstance();
            XmlPullParser parser = parserCreator.newPullParser();
            
            parser.setInput(text.openStream(), null);
            
            
            
            int eventType = parser.getEventType();
            boolean inSuccessTag = false;
            
            while (eventType != XmlPullParser.END_DOCUMENT)
            {
                if (eventType == XmlPullParser.START_TAG)
                {
                    if(parser.getName().equals("Success"))
                        inSuccessTag = true;
                }
                else if (eventType ==XmlPullParser.END_TAG)
                {
                    inSuccessTag = false;
                }
                else if (eventType ==XmlPullParser.TEXT)
                {
                    if (inSuccessTag)
                    {
                        Log.d("","Found SUCCESS tag");
                        Log.d("","The authvalue SUCCESS is"+parser.getText());
                        
                        
                    }
                }
                
                eventType = parser.next();
            }
        }
        catch (Exception e)
        {
            Log.e("Net", "Error in network call", e);
        }
    }
