How do I generate text matching a regular expression from a regular expression? [closed]

Answer 1

I just created a library for doing this a minute ago. It's hosted here: http://code.google.com/p/xeger/. Carefully read the instructions before using it. (Especially the one referring to downloading another required library.) ;-)

This is the way you use it:

String regex = "[ab]{4,6}c";
Xeger generator = new Xeger(regex);
String result = generator.generate();
assert result.matches(regex);
