How to read JavaScript output text in a Java Program
Question
Hi i am trying to read forbes.com 's thought of the day in my Java program. But in the view source of the webpage i am not getting the output rendered on the html page. Any clues as to how to read the rendered output?
Heres the source code of website where i am reading the thoughts from.
<head>
<script src="http://images.forbes.com/scripts/dart_forbes.js"></script>
<script src="http://images.forbes.com/welcome/desktop/welcome_js.js?v=1.5"></script>
</head>
<body>
<script language="JavaScript">
forbes_dart.ad('thoughtx', '600x100');
</script>
</body>
I have minimised and removed all clutter and kept it as basic as possible.
Heres the view source of the site
<html>
<head>
<script src="./js/dart_forbes.js"></script>
<script src="./js/welcome_js.js"></script>
</head>
<body>
<script language="JavaScript">
forbes_dart.ad('thoughtx', '600x100');
</script>
</body>
</html>
Here's my Java program
public class extractor {
public static void main(String args[]) throws Exception{
extractor t = new extractor();
t.connect();
}
public void connect() throws Exception {
URL obj = new URL("http://localhost:8080/q2p/thought.html");
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
System.out.println(response.toString());
}
}
Here's the program output
<html> <head> <script src="./js/dart_forbes.js"></script> <script src="./js/welcome_js.js"></script> </head> <body> <script language="JavaScript"> forbes_dart.ad('thoughtx', '600x100'); </script> </body></html>
[SOLUTION]
Well after some help from meister_reineke heres the java code which works :) and solves the problem.
public class extractor {
public static void main(String args[]) throws Exception{
extractor t = new extractor();
t.connect();
}
public void connect() throws Exception {
URL obj = new URL("http://localhost:8080/q2p/thought.html");
WebClient webClient = new WebClient(BrowserVersion.CHROME);
HtmlPage myPage = ((HtmlPage) webClient.getPage(obj));
System.out.println(myPage.asText());
webClient.closeAllWindows();
}
}
The output for the above code is
Patience strengthens the spirit, sweetens the temper, stifles anger, extinguishes envy, subdues pride, bridles the tongue.
