Thanks for the quick answer guys.

Unfortunately four groups is not going to help, it should match anthing from 1.2 to 1.2.3.4.5.6 etc, or anything follows this structure.

To look for a substring matching  [\d+\.]+ is also not an option, as there may be other matches in the string, like a simple number.
