Jakarta Regexp 1.5 Backreferences?
- by Matt Smith
Why does this match:
String str = "099.9 102.2" + (char) 0x0D;
RE re = new RE("^([0-9]{3}.[0-9]) ([0-9]{3}.[0-9])\r$");
System.out.println(re.match(str));
But this does not:
String str = "099.9 102.2" + (char) 0x0D;
RE re = new RE("^([0-9]{3}.[0-9]) \1\r$");
System.out.println(re.match(str));
The back references don't seem to be working... What am I missing?
