需要解析的xml文件如下：

<girl>
    	<name>
    		raid
    	</name>
    	<age>
    		12
    	</age>
    	<school>
    		zhongkai
    	</school>
    </girl>

解析方法如下，这里结合了网络传输给出代码：

url是xml资源所在的位置

try {
    			URL httpUrl = new URL(url);
    			HttpURLConnection conn = (HttpURLConnection) httpUrl.openConnection();
    			conn.setRequestMethod("GET");
    			conn.setReadTimeout(5000);
    			InputStream in = conn.getInputStream();
    			
    			XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
    			XmlPullParser parser = factory.newPullParser();
    			parser.setInput(in, "UTF-8");
    			int eventType = parser.getEventType();
    			final List<Girl> list = new ArrayList<Girl>();
    			Girl girl = null;
    			while(eventType != XmlPullParser.END_DOCUMENT) {
    				String data = parser.getName();
    				switch (eventType) {
    				case XmlPullParser.START_TAG:
    					if ("girl".equals(data)) {
    						girl = new Girl();
    					}
    					if ("name".equals(data)) {
    						girl.setName(parser.nextText());
    					}
    					if ("age".equals(data)) {
    						girl.setAge(Integer.parseInt(parser.nextText().trim()));
    					}
    					if ("school".equals(data)) {
    						girl.setSchool(parser.nextText());
    					}
    					break;
    					
    				case XmlPullParser.END_TAG:
    					if ("girl".equals(data) && girl!=null) {
    						list.add(girl);
    					}
    					break;
    				}
    				//必须记住要添加这个方法
    				eventType = parser.next();
    			}
    			
    			handler.post(new Runnable() {
    				
    				@Override
    				public void run() {
    					// TODO Auto-generated method stub
    					textView.setText(list.toString());
    				}
    			});
    			
    		} catch (MalformedURLException e) {
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		} catch (IOException e) {
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		} catch (XmlPullParserException e) {
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		}
    	}
