replace ';' LIST ';' REGEX ';' REPLACE (';' STRING)?

Replace all elements of the list that match the regular expression regex with the replacement. The replacement can use the $[0-9] back references defined in the regular expressions. The macro uses item.replaceAll(regex,replacement) method to do the replacement.For example, to add a .jar extension to all files listed, use the following: \</td> List = ${replace;${impls};$;.jar}

/**
 * replace ; <list> ; regex ; replace
 *
 * @param args
 * @return
 */
public String _replace(String args[]) {
	if (args.length < 4 || args.length > 5) {
		domain.warning("Invalid nr of arguments to replace " + Arrays.asList(args));
		return null;
	}

	String middle = ", ";
	if ( args.length > 4)
		middle = args[4];


	String list[] = args[1].split("\\s*,\\s*");
	StringBuilder sb = new StringBuilder();
	String del = "";
	for (int i = 0; i < list.length; i++) {
		String element = list[i].trim();
		if (!element.equals("")) {
			sb.append(del);
			sb.append(element.replaceAll(args[2], args[3]));
			del = middle;
		}
	}

	return sb.toString();
