  File file = new File("f:\\email.html");
  BufferedReader reader = new BufferedReader(new FileReader(file));
  String line = null;
  String reg = "[a-zA-Z_0-9]+@[a-zA-Z0-9]+([url=file://\\.[a-z]{2,}){1,2]\\.[a-z]{2,}){1,2[/url]}";
  Pattern p = Pattern.compile(reg);
  while((line=reader.readLine())!=null){ //每次读一行
   Matcher m = p.matcher(line);
   while(m.find()){
