problem while parsing script tag from HTMLEditorKit

Posted: Nov 11, 2004 12:46 AM

HI,
I have written the following program called process.java to parse a file called login.html which is also given below. But I am not able to get the data which is in <SCRIPT></SCRIPT> tag. Check out the output I got for the process.java. One more thing I getting "?" in place of &nbsp when I copy the output and run it.
Please find out the errors and give me the solution for two problems.

process.java
------------

import java.util.*;
import java.io.*;
import javax.swing.text.*;
import javax.swing.text.html.*;
import javax.swing.text.html.parser.*;
import java.net.*;
import ParserGetter.*;

class parse1 extends HTMLEditorKit.ParserCallback
{
StringBuffer sb=new StringBuffer();
public void handleText(char[] text,int position)
{
sb.append(text);
System.out.println(text);
}
public void handleEndTag(HTML.Tag tag,int position)
{
sb.append("<").append("/").append(tag).append(">");
System.out.println("<"+"/"+tag+">");
}
public void handleSimpleTag(HTML.Tag tag,MutableAttributeSet attributes,int position)
{
int ind=0;
String store1="";
String tok[]=new String[50];
sb.append("<").append(tag);
System.out.print("<"+tag);
Enumeration e=attributes.getAttributeNames();
while(e.hasMoreElements())
{
Object name=e.nextElement();
Object value=attributes.getAttribute(name);
sb.append(" ").append(name).append("=").append(value);
System.out.print(" "+name+"="+value);
}
sb.append(">");
System.out.print(">");
System.out.println();
}
public void handleStartTag(HTML.Tag tag,MutableAttributeSet attributes,int position)
{
sb.append("<").append(tag);
System.out.print("<"+tag);
Enumeration e=attributes.getAttributeNames();
while(e.hasMoreElements())
{
Object name=e.nextElement();
Object value=attributes.getAttribute(name);
sb.append(" ").append(name).append("=").append(value);
}
sb.append(">");
System.out.print(">");
}

}

public class process
{
ParserGetter kit=null;
HTMLEditorKit.Parser parser=null;
public process()
{
kit=new ParserGetter();
parser=kit.getParser();
try
{
URL u=new URL("http://localhost:8080/examples/jsp/project/login.html");
URLConnection uc = u.openConnection();
InputStream in=u.openStream();
in=new BufferedInputStream(in);
Reader r=new InputStreamReader(in);
parse1 p=new parse1();
HTMLEditorKit.ParserCallback call=p;
parser.parse(r,call,true); //ignores the charaset
}
catch(Exception e)
{
e.printStackTrace();
}
}
public static void main(String a[])
{
new process();
}
}
