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

[Russell Hind]

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 '-'

If we print some pages ,we can select pages in a range to print.
for example,if we enter 2,3,5-7 in Ms-word print dialog,then page
2,3,5,6,7 is printed.
Now questions is :
if we get a string like this "2,3,5-7",if we use boost::tokenizer,
we can only get 2,3,5,7. eventually some information is lost.
How can we get the desired result----"2,3,5,6,7" using boost::tokenizer?
