[Boost-users] [Regex] Group of number at line end

Hallo regex gurus, i am looking for a regular expression which extracts a group of number from the end of a line like the following: "This line may contain digits (9) but ends with numbers like 1 2 3 4 5" When using a regex like "^(.+)(\\s+(\\d+))+$" I receive "This line may contain digits (9) but ends with numbers like 1 2 3 4" and "5". Can someone help me? RHutsch
