按照视频中的例子做，出现如下错误：
web项目运行正常，如访问：http://localhost:8088/videoweb/video/list.do
返回的xml为：
<?xml version="1.0" encoding="UTF-8" ?>

这些短横线不知道是什么东东。
android项目是想解析这个xml文件，解析器的代码如下：
public class VideoService {
public static List getLastVideos() throws Exception{
String path = "http://192.168.1.100:8088/videoweb/video/list.do";
URL url = new URL(path);
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
conn.setReadTimeout(5*1000);
conn.setRequestMethod("GET");
InputStream inStream = conn.getInputStream();
byte[] buffer = new byte[1024];
int len = 0;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
while((len=inStream.read(buffer))!=-1){
bos.write(buffer, 0, len);
}
return parseXML(inStream);
}

private static List parseXML(InputStream inStream) throws Exception{
List videos = null;
Video video = null;
XmlPullParser parser = Xml.newPullParser();
parser.setInput(inStream, "UTF-8");
int eventType = parser.getEventType();//产生第一个事件
while(eventType!=XmlPullParser.END_DOCUMENT){//只要不是文档结束事件
switch (eventType) {
case XmlPullParser.START_DOCUMENT:
videos = new ArrayList();
break;

    case XmlPullParser.START_TAG:
        String name = parser.getName();//获取解析器当前指向的元素的名称
        if("video".equals(name)){
            video = new Video();
            video.setId(new Integer(parser.getAttributeValue(0)));
        }
        if(video!=null){
            if("title".equals(name)){
                video.setTitle(parser.nextText());//获取解析器当前指向元素的下一个文本节点的值
            }
            if("timelength".equals(name)){
                video.setTime(new Integer(parser.nextText()));
            }
        }
        break;
    case XmlPullParser.END_TAG:
        if("video".equals(parser.getName())){
            videos.add(video);
            video = null;
        }
        break;
    }
    eventType = parser.next();
}
return videos;

}

}
而activity代码如下：
public class VideoClientActivity extends Activity {
private ListView listView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

listView = (ListView)this.findViewById(R.id.listView);
try {
    List<Video> videos = VideoService.getLastVideos();
    List<HashMap<String, Object>> data = new ArrayList<HashMap<String,Object>>();
    for(Video video : videos){
        HashMap<String, Object> item = new HashMap<String, Object>();
        item.put("id", video.getId());
        item.put("title", video.getTitle());
        item.put("timelength", "时长:"+ video.getTime());
        data.add(item);
    }
    Log.i("size", videos.size()+"");
    SimpleAdapter adapter = new SimpleAdapter(this, data, R.layout.item, 
            new String[]{"title", "timelength"}, new int[]{R.id.title, R.id.timelength});
    listView.setAdapter(adapter);
} catch (Exception e) {
    Toast.makeText(VideoClientActivity.this, "获取最新视频资讯失败", 1).show();
    Log.e("VideoClientActivity", e.toString());
}

}
}
在LogCat中添加一个过滤器：VideoClientActivity，出现的错误是：
[color=red]11-13 08:14:21.303: ERROR/VideoClientActivity(365): org.xmlpull.v1.XmlPullParserException: Premature end of document. (position:line

-1, column -1) caused by: org.apache.harmony.xml.ExpatParser$ParseException: At line 1, column 0: no element found[/color]
请各位大侠解救。 :(
