		Pattern pattern = Pattern.compile(regexp, Pattern.CASE_INSENSITIVE);
		Matcher matcher = pattern.matcher(s);
		StringBuffer sb = new StringBuffer();
		while (matcher.find()) {
			String p = matcher.group();
			matcher.appendReplacement(sb, "\""+p+"\"");
		}
		matcher.appendTail(sb);
		return sb.toString();
