Beautiful Soup 4 works on both Python 2 (2.6+) and Python 3.
Beautiful Soup is licensed under the MIT license, so you can also download the tarball, drop the bs4/ directory into almost any Python application (or into your library path) and start using it immediately. If you want to do this under Python 3, you will need to manually convert the code using 2to3.
