 public String getTagA_href_Value(String html) {
  Pattern p = Pattern.compile("([ ]+href[ ]*=\")([^\"]+)\"");
  Matcher m = p.matcher(html);
  if (m.find())
  {
   System.out.println(m.group(0));
   System.out.println(m.group(1));
   System.out.println(m.group(2));
   System.out.println("----------------");
   return m.group(2);
  }
  return "";
 }

2. HTML 태그 없애기

 public String getTagA_String(String html) {
  Pattern p = Pattern.compile("\\<(\\/?)(\\w+)*([^<>]*)>");
     Matcher m = p.matcher(html);
  if (m.find()) {
   return m.replaceAll("");
  }
  return "";
