    Default Retrieve Text From A Webpage

    Hello, I would like to know how I could retrieve text from a webpage without getting all the code in it. I tried this:
    Java Code: 
    try {
			url = new URL("http://multibin2.comeze.com/");
			

			    BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
			    
			    String str;
			    pan = new JEditorPane();
			    
			    JScrollPane p = new JScrollPane(pan);
			    add(p);
			    while ((str = in.readLine()) != null) {
			    	
					pan.setText(pan.getText() + "\n" + str);
					
			      System.out.println(str); 
			    }
			    in.close();
			    
		} catch (MalformedURLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		try {
			System.out.println(url.getContent());
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
    but of course it ends up giving me everything:
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <meta http-equiv="Content-Style-Type" content="text/css">
    <title></title>
    <meta name="Generator" content="Cocoa HTML Writer">
    <meta name="CocoaVersion" content="1138">
    <style type="text/css">
    p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Times}
    </style>
    </head>
    <body>
    <p class="p1">@1@</p>
    <p class="p1">@Nothing New Has Been Added@</p>
    </body>
    </html>

    What I would like to get out of this is just the "@1@" and the "@nothing new has been added@"

    Default Re: Retrieve Text From A Webpage

    the JVM has built in classes to parse XML. Take time to look at DOM manipulation examples using the classes found in javax.xml and you will easily be able to parse out the data you want from the page you are downloading.
