[boost] Re: How to achieve this goal using boost::tokenizer?

You need to pass a separator into the tokenizer that only separates on 
',' (i'm not sure if this code compiles, but you get the idea

std::string Pages("2,3,5-7");
char_separator<char>             CommaSep(",");
tokenizer<char_separator<char> > Tokenizer(Pages,CommaSep);

This will split it up into

2
3
5-7

You will then need to do a bit of extra passing on each token to see if 
it is a range (contains a '-') using either just a find, or create 
another tokenizer for '-'
