    private String currentString = "";
    private String charactersString = "";
    private Branch branch;
    private Year year;
    private Semester semester;
    private int branchCount = 0;
    private int yearCount = 0;
    private int semesterCount = 0;

//  private ArrayList<Gtudownload> itemsList = new ArrayList<Gtudownload>();
//  
//  public ArrayList<Gtudownload> getItemsList() {
//      return itemsList;
//  }

    public Gtudownload getGtudownload(){
        return this.gtudownload;
    }
    public Questionpaper getQuestionpaper()
    {
        return this.questionpaper;
    }


    // Called when tag starts
    @Override
    public void startElement(String uri, String localName, String qName,
            Attributes attributes) throws SAXException {
        Log.i("GTU ", localName);
        if (localName.equalsIgnoreCase("Gtudownload")) {
            gtudownload = new Gtudownload();
            currentString = "Gtudownload";

        } else if (localName.equalsIgnoreCase("Questionpaper")) {
            gtudownload.setQuestionpaper(new Questionpaper());
            gtudownload.getQuestionpaper().setBranchList(new ArrayList<Branch>());
            currentString = "Questionpaper";
        } else if (localName.equalsIgnoreCase("Branch")) {
            branch = new Branch();
            gtudownload.getQuestionpaper().getBranchList().add(branch);
            gtudownload.getQuestionpaper().getBranchList().get(branchCount).setYearList(new ArrayList<Year>());
            currentString = "Branch";
            Log.i("Branch", attributes.getValue("value"));
            branch.setValue(attributes.getValue("value"));
        } else if (localName.equalsIgnoreCase("Year")) {

    }

}

this is my activity and how can i set this parsing data in into textview

    public class GtudldActivity extends Activity {
    /** Called when the activity is first created. */
    private TextView xmlOutput;
    TextView example[];

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

        xmlOutput = (TextView) findViewById(R.id.xmlOutput);

        Gtudownload gtudownload = parseXML();

    }

    private Gtudownload parseXML() {

        Gtudownload gtudownload = null;

        try {

            Log.w("AndroidParseXMLActivity", "Start");
            /** Handling XML */
            SAXParserFactory spf = SAXParserFactory.newInstance(); 
            SAXParser sp = spf.newSAXParser();       
            XMLReader xr = sp.getXMLReader(); 

            GtuItemXMLHandler myXMLHandler = new GtuItemXMLHandler();
            xr.setContentHandler(myXMLHandler);
            InputSource is = new InputSource(getResources().openRawResource(R.raw.mgtu));


            gtudownload = myXMLHandler.getGtudownload();

            Log.i("Data",gtudownload+"");
            xr.parse(is);

        } catch (Exception e) {
            Log.w("AndroidParseXMLActivity", e);
        }

        //xmlOutput.setText(gtudownload.toString());

        return gtudownload;

    }
}
