ANDROID - Sax Parsing (Using Url)

Demo:

1)SaxParsing Activity:

package com.venkool;

import java.io.IOException;

import java.io.InputStream;

public class SaxParsing extends Activity {

    /** Called when the activity is first created. */

     

      InputStream is;

      SAXParser saxParser;

      ListView lvList;

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

       

        lvList=(ListView)findViewById(R.id.lvList);

       

       

       

        try {

            saxParser=SAXParserFactory.newInstance().newSAXParser();

                  is=new DefaultHttpClient().execute(

                              new HttpGet("http://www.xmlfiles.com/examples/cd_catalog.xml")).getEntity().getContent();

                  saxParser.parse(is, new MyHandler());

            } catch (IllegalStateException e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

            } catch (ClientProtocolException e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

            } catch (IOException e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

            } catch (SAXException e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

            } catch (ParserConfigurationException e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

            }

           

            lvList.setAdapter(new MyArrayAdapter(new MyHandler().getData(),SaxParsing.this));

    }

}
