  public class xml2Instance {
  	public static void main(String[] args){
  		SAXReader reader = new SAXReader();
  		
  		try {
  			Document doc =  reader.read
  					(new FileInputStream("C:/Users/Administrator/Desktop/first.xml"));
  			Element root = doc.getRootElement();
  			Customer customer = new Customer();
  			System.out.println(root.attributeValue("CustName"));
  			customer.setCustName(root.attributeValue("CustName"));
  			customer.setType(root.attributeValue("Type"));
  			customer.setDest(root.attributeValue("Dest"));

heroes , and why I can not read file values ​​, um, I was just using dom4j first.xml written , but it is there ah

------ Solution ----------------------------------- ---------
xml file you do not know what kind , but feel you should have no access to the outer Customer (); object
give you one example

  public Map<String, String> getProvinceMap() {
  		Map<String, String> proMap = new HashMap<String, String>();
  		try {
  			InputStream in = DBHelper.getDBHelper().getContext().getResources()
  					.getAssets().open("province.xml");
  			InputStream is = IOHelper.fromInputStreamToInputStreamInCharset(in,"utf-8");
  			SAXReader sr = new SAXReader();// 获取读取xml的对象。
  			Document document = sr.read(is);
  			Element root = document.getRootElement();
  			List<?> elementlist = root.elements("city");
  			for (Object obj : elementlist) {
  				Element row = (Element) obj;
  				String quName = row.attribute("quName").getText();
  				String pyName = row.attribute("pyName").getText();
  				proMap.put(quName, pyName);
  			}
  		} catch (Exception e) {
  			Log.e("tag", "read configure error");
  		}
  		return proMap;
  	}
