HTML to TXT

Question

Hello,
I've got the code allowing to change HTML files to TXT.
import javax.swing.text.html.parser.*;
import javax.swing.text.html.*;
import javax.swing.text.*;
import javax.swing.*;
import java.io.*;
public class TextFromHtml extends HTMLEditorKit.ParserCallback{
  static Reader r;
  static PrintWriter pw;
  public static String trimmss(String o){return (o.trim()).replaceAll("\\s+", " ");}
  public void handleText(char[] data, int pos){
       String o = new String(data);
     o = trimmss(o);
     pw.println(o);
public static void main(String args[]){
String s = null;
String f = null;
int i = 0;
while ((s = args) != null){
try{
     r = new FileReader(s);
     f = s.substring(0, s.lastIndexOf('.')) + ".txt";
     pw = new PrintWriter(new BufferedWriter(new FileWriter(f)));
     ParserDelegator parser = new ParserDelegator();
     HTMLEditorKit.ParserCallback callback = new TextFromHtml();
     parser.parse(r, callback, true);
     pw.close();
     r.close();
     ++i;
     catch (IOException e){e.printStackTrace();}
System.exit(0);
but after invoking by: java TextFromHtml C:/html/*.html I obtain only the result for file 0.html, which is converted to 0.txt. Other files, 1,2,3,4,5.html are not converted. Could you help me and tell why?
Regards, Karel

Your code has a few issues:
If you use a wildcard as arg[0], it will come in as a String, not a list of files
Your loop counts the length of arg[], since you submit only one argument, it only gets executed once as file 0 (since that is what 'i' evaluates to). If you wanted to process five files, under your design, you would need five, separate command-line args.- Saish
