如何从 xml 中保存换行符？

Question

当我从此页面检索歌词时： 这里，换行符消失了。我在单个字符串中检索 xml，为了简单起见，我使用子字符串来减去歌词。当我使用以下代码打印每个字符时，看不到换行符。

if (response.contains("lyrics_body")) {
            lyrics = response.substring(response.indexOf("<lyrics_body>") + 13, response.indexOf("</lyrics_body>"));
            StringReader sr = new StringReader(lyrics);
            int l;
            try {
                while ((l = sr.read()) != -1) {
                    System.out.println(":" + l);
                }
            } catch (Exception ex) {

            }
        }

部分输出：

85  U
104 h
110 n
32  
116 t
105 i
115 s
115 s
32  
117 u
104 h
110 n
32
116 t
105 i
115 s
115 s
32  
117 u
104 h
110 n
32  
116 t
105 i
115 s
115 s
32
98  b
97  a
98  b
121 y
68  d   
111 o
103 g
32
119 w
105 i
108 l
108 l
.
.

为了清楚起见，我在数字后面添加了各个字符，显然在“baby”和“dog”之间应该有一个换行符。

我怎样才能解析这个换行符？

Answer 1

我从某个地方使用了这个来源：

public static String postData(String base, List<BasicNameValuePair> data) throws IOException {
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(base);
    HttpResponse response = null;
    String line = "";
    StringBuilder total = new StringBuilder();
    HttpProtocolParams.setUseExpectContinue(httpclient.getParams(), false);

    try {
        httppost.setEntity(new UrlEncodedFormEntity(data));

        // Execute HTTP Post Request
        response = httpclient.execute(httppost);

        // Wrap a BufferedReader around the InputStream
        BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

        // Read response until the end
        while ((line = rd.readLine()) != null) {
            total.append(line);
            total.append("\n"); //I'VE JUST ADDED THIS LINE
        }

    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    // Return full string
    return total.toString();
}

显然，它说“我刚刚添加了这一行”的部分是问题所在，感谢乔恩让我查看这段代码！

将 StringReader 包装在 BufferedReader 中并使用 readLine()

    BufferedReader bufferedReader = new BufferedReader(new StringReader(lyrics));

    for (String line = bufferedReader.readLine(); line != null; line = bufferedReader.readLine()) {
        // do something with line
    }
