如何從xml保存換行符？

Question

當我從以下頁面檢索歌詞時： 此處 ，換行符消失。 我以單個String檢索xml，為簡單起見，我使用子字符串減去歌詞。 當我使用以下代碼打印每個字符時，看不到換行符。

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) {

            }
        }

部分輸出：

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
.
.

為了清楚起見，我在數字后面添加了單個字符，顯然在“ baby”和“ dog”之間應該有換行符。

如何解析此換行符？

Answer 1

我從某處使用過此來源：

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();
}

顯然，出現問題“我剛剛添加了這一行”的部分就是問題，感謝喬恩讓我看過這段代碼！

將StringReader包裝在BufferedReader並使用readLine()

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

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