Taking data from rss feed using xml and then storing in an ArrayList

This is an example what I had done, you can look at this and work accordingly,

MainRSSDemo.java

public class MainRSSDemo extends Activity {

    private List<Message> messages;
    static String feedUrl = "http://rss.news.yahoo.com/rss/terrorism";
    static final String RSS = "rss";
    static final String CHANNEL = "channel";
    static final  String ITEM = "item";
    static final String PUB_DATE = "pubDate";
    static final  String DESCRIPTION = "description";
    static final  String LINK = "link";
    static final  String TITLE = "title";
    static final  String URL = "url";
    static final  String MEDIA = "content";
    private InputStream is;
    private URL feed_Url = null;
    private ListView lv;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        lv =(ListView)findViewById(R.id.ListView01);

        try {
                feed_Url = new URL(feedUrl);
                is =  feed_Url.openConnection().getInputStream();
                messages = parse();
                is.close();

        } catch (Exception e) {
            Log.i("err", e.toString());
            e.printStackTrace();
        }

        final List<String> titles = new ArrayList<String>(messages.size());
        for (Message msg : messages){
            titles.add(msg.getTitle());
        }
        lv.setAdapter(new ArrayAdapter<String>(this,R.layout.row,titles));
        lv.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int position,long id) {

                Toast.makeText(getBaseContext(),titles.get(position), Toast.LENGTH_LONG).show();

        }
        });
    }

    public List<Message> parse() {
        List<Message> messages = null;
        XmlPullParser parser = Xml.newPullParser();
        try {
            parser.setInput(is, null);
            int eventType = parser.getEventType();
            Message currentMessage = null;
            boolean done = false;
            while (eventType != XmlPullParser.END_DOCUMENT && !done){
                String name = null;
                switch (eventType){
                    case XmlPullParser.START_DOCUMENT:
                        messages = new ArrayList<Message>();
                        break;
                    case XmlPullParser.START_TAG:
                        name = parser.getName();
                    if (name.equalsIgnoreCase(ITEM)) {
                        currentMessage = new Message();
                    } else if (currentMessage != null) {
                        if (name.equalsIgnoreCase(LINK)) {
                            currentMessage.setLink(parser.nextText());
                        } else if (name.equalsIgnoreCase(DESCRIPTION)) {
                            String parse = parser.nextText().toString();
                            if (parse.contains("</a>")) {
                                parse = parse.substring(parse.indexOf("</a>") + 4, parse.lastIndexOf("</p>"));
                                currentMessage.setDescription(parse.toString());
                            } else {

                        }
                    }
                        break;
                    case XmlPullParser.END_TAG:
                        name = parser.getName();
                        if (name.equalsIgnoreCase(ITEM) && currentMessage != null){
                            messages.add(currentMessage);
                        } else if (name.equalsIgnoreCase(CHANNEL)){
                            done = true;
                        }
                        break;
