The short answer is you can't - only the last group is accessible. The Python docs state this explicitly:

If a group matches multiple times, only the last match is accessible [...]

You'll have to use some language features:

1. In PHP, there's preg_match_all that returns all matches.
2. In other languages, you'll have to do this manually: add the g modifier to the regex and loop over it. Perl, for example, will manage a string position and return the next match in $1 each time a /([...])/g pattern is matched.
