Question

When I retrieve lyrics from this page: here, the newlines disappear. I retrieve the xml in single String, and for simpleness for this question I use substring to subtract the lyrics. When I print each character using the following code, no newlines are visible.

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) {

            }
        }

Part of the output:

85  U
104 h
110 n
32  
116 t
105 i
115 s
115 s
32  
117 u

119 w
105 i
108 l

.

I’ve added the individual chars behind the numbers for clarity, and obviously between ‘baby’ and ‘dog’ there should be a newline.

How can I parse this newline?

Answer 1

I’ve used this source from somewhere:

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();
}

Obviously, the part where it says “I’ve just added this line” was the problem, thanks Jon for making me look in this code!
