[Boost-users] Extracting items from a string

Hi: I have a string of the following format: 11, 0, 1461, 400 I need to be able to extract any element of the string at any point, so for example, the 1, would return 11, or the second world return 0. What is the best way of extracting any individual element, without using any temporary variables. IF I use boost.tokenizer, can I access any element individually, without using iterators? Or is there a better way of dealing with this sort of string. Any help appreciated. Cheers Sean.
