通过搜索获得音乐文件和相应LRC文件的绝对路径

// 请求服务器获取xml文件
	public String getMusicXML(String musicName, String singerName) {
		 
		try {
			musicName = URLEncoder.encode(musicName,"gbk");
			singerName = URLEncoder.encode(singerName,"gbk");
		} catch (UnsupportedEncodingException e2) {
			// TODO Auto-generated catch block
			e2.printStackTrace();
		}
		String strUrl = "http://box.zhangmen.baidu.com/x?op=12&count=1&title="
				+ musicName + "$$" + singerName + "$$$$";		
		Log.e("url", strUrl);
		try {
			url = new URL(strUrl);
		} catch (Exception e1) {
			e1.printStackTrace();
		}
		
		BufferedReader br = null;
		String s;
		try {
			InputStreamReader in = new InputStreamReader(url.openStream());
			Log.e("the encode is ", in.getEncoding());
			br = new BufferedReader(in);
		} catch (IOException e1) {
			Log.e("tag", "br is null");
		}

		try {

			while ((s = br.readLine()) != null) {
				sb.append(s + "\r\n");
				br.close();
			}
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		Log.e("sb=", sb.toString());
		return sb.toString();
	}

获得的xml文件如下：

解析xml文件，获得String musicPath  String lrcPath：

// 解析xml文件，得到music文件和lrc文件的地址
	public String getLyricPath() {   
        int begin = 0, end = 0, number = 0;   
        String lrcPath = "";   
        begin = sb.indexOf("<lrcid>");      
        Log.e("test", "sb = " + sb); 
  
        if (begin != -1) {   
            end = sb.indexOf("</lrcid>", begin);   
            lrcPath = sb.substring(begin + 7, end);   
            number = Integer.parseInt(lrcPath);   
        }   
  
      	lrcPath = "http://box.zhangmen.baidu.com/bdlrc/" + number / 100  
               + "/" + number + ".lrc";   
        Log.e("test", "lrcPath = " + lrcPath);
		return lrcPath; 
        }   
	

	public String getMusicPath(){
		int begin = 0, end = 0;
        String musicPath = "";   
        begin = sb.indexOf("<p2p>");
        if(begin != -1){
        	end = sb.indexOf("</p2p>", begin);
        	musicPath = sb.substring(begin, end + 5);
        }
        begin = musicPath.indexOf("http://");  
        if (begin != -1) {   
            end = musicPath.indexOf("]]>");   
            musicPath = musicPath.substring(begin, end); 
        }   
        Log.e("test", "musicPath = " + musicPath);
		return musicPath;		
	}

得到的musicPath = "http://zhangmenshiting.baidu.com/data2/music/5219955/5219955.mp3?xcode=de853ab52489ef65d21c0ed7334abdcd"

lrcPaht = "http://box.zhangmen.baidu.com/bdlrc/147/14706.lrc"

其中musicPaht会改变，lrcPath不变
