README

named-regexp

This library backports named capture groups from Java 7 to Java 5/6.

Usage

You can use the same constructs for named capture groups from Java 7 (i.e., (?<name>patt), etc.), as in the following example:

import com.google.code.regexp.Pattern;
import com.google.code.regexp.Matcher;
public class NamedRegexpTest {     public static void main(String[] args) {         // pattern contains capture group, named "foo"         Matcher m = Pattern.compile("(?<foo>\\w+) world").matcher("hello world!");         m.find();         System.out.println(m.group("foo")); // prints "hello"     } }
