How to get text of an HTML file?

Question

I wish to get the content of an HTML file (as is displayed in a browser). This is my code:
FileInputStream fis = new FileInputStream("myfile.html");
HTMLEditorKit kit = new HTMLEditorKit();
HTMLDocument document = new HTMLDocument();
kit.read(fis, document, 0);
String content = document.getText(0, document.getLength());But content returns null.
Can someone tell me what is wrong? Thank you!

Yeah, open a URL and read the contents from that input stream. That'll bring the URL down to your machine.
This will do it:
package vampire;
import java.io.BufferedReader;
import java.io.FileWriter;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.URL;
* Simple program for demonstrating the URL class.
public class URLVampire
     * Driver for reading the contents of a URL
     * @param command line arguments.
    public static void main(String [] args)
        if (args.length == 0)
            System.err.println("Usage: java URLVampire <URL 1> <URL 2>...<URL n>");
            System.exit(0);
        try
            String [] urlContents = new String[args.length];
            for (int i = 0; i < args.length; ++i)
                URL url                 = new URL(args);
System.out.println("Now reading the contents of URL " + args[i]);
InputStream uis = url.openStream();
InputStreamReader isr = new InputStreamReader(uis);
BufferedReader br = new BufferedReader(isr);
StringBuffer buffer = new StringBuffer();
String line = null;
while ((line = br.readLine()) != null)
buffer.append(line);
br.close();
System.out.println("Read " + buffer.length() + " chars for URL " + args[i]);
urlContents[i] = buffer.toString();
// Now write out all the URL contents
for (int i = 0; i < urlContents.length; ++i)
PrintWriter pw = new PrintWriter(new FileWriter("url" + i + ".html"));
pw.println("<!-- URL: " + args[i] + "-->");
pw.println(urlContents[i]);
pw.close();
catch (Exception e)
e.printStackTrace(System.err);
