안드로이드 XML파싱시 문제가 있습니다. 도와주세요 ㅠ

Question

public class select_Thread extends Activity implements Runnable {
	public static ArrayList<Thread_result> rdata = new ArrayList<Thread_result>();

	Handler handler = new Handler() {
		public void handleMessage(Message msg) {
			if (msg.obj != null)
				rdata.add((Thread_result) msg.obj);
		}

	};

	public void run() {

		try {
			String enter = "basic_select_copy";
			URL connection = new URL("http://203.247.41.242/" + enter + ".php");
			connection.openStream();
			URL server = new URL("http://203.247.41.242/" + enter + ".xml");

			XmlPullParserFactory parserCreator = XmlPullParserFactory
					.newInstance();
			XmlPullParser parser = parserCreator.newPullParser();
			InputStream is = server.openStream();

			parser.setInput(is, "UTF-8");

			int parserEvent = -1;
			String START = "";
			String TEXT_TAG = "deflut";
			String END = "";
			String nameTag = null, Number = null, locationTag = null;

			while (parserEvent != XmlPullParser.END_DOCUMENT) {

				switch (parserEvent) {
				case XmlPullParser.START_TAG:
					START = parser.getName();
//					Log.i("START", parser.getName());
					break;

				case XmlPullParser.TEXT:
					TEXT_TAG = parser.getText();
//					Log.i("TEXT", parser.getText());
					break;

				case XmlPullParser.END_TAG:
					END = parser.getName();
//					Log.i("END", parser.getName());
					break;

				}
				Message msg = Message.obtain();

				if (START.equals(END)) {
					//Log.i("START", START);
					if (START.equals("item_number")) {
						Number = "test";
						Number = TEXT_TAG;
						Log.i("here1", Number);

					} else if (START.equals("name")) {
						nameTag = TEXT_TAG;
						Log.i("here2", Number);
					} else if (START.equals("location")) {
						locationTag = TEXT_TAG;
//						Log.i("name", nameTag);
						Log.i("number", Number);
//						Log.i("loca", locationTag);
						Thread_result tdata = new Thread_result(nameTag, Number, locationTag);
						msg.what = 3;
						msg.obj = tdata;
						Log.i("tdata", tdata.getNumber());
						handler.sendMessage(msg);
					}

				}

				parserEvent = parser.next();
			}

위는 자바 소스 파일이고요 XML파일 파싱한 뒤 START태그와 END태그가 같으면 내용을 TEXT_TAG 에 저장합니다. 그리고 그 TEXT_TAG의 내용하고 값을 비교해서 객체를 선언한뒤 핸들러로 객체를 반환하는 내용입니다.

아래는 XML파일입니다.

문제는 Thread_result tdata = new Thread_result(nameTag, Number, locationTag); 

분입니다. 객체를 만들 시 nameTag와 locationTag는 값이 정상적으로 전달되는데 비하여 Number은 

if (START.equals("item_number")) {
						Number = "test";
						Number = TEXT_TAG;
						Log.i("here1", Number);

					} 

에서는 값이 정상적으로 나오는데 객체를 생성 할  시 아무런 값도 찍히지 않습니다.
