[Boost-users] Mismatch and regex newbie problem still problem

So to sum-up.
If the regex i'm looking for is "testing" and the string to search the regex 
for is "tastung" (obviously this is a short example but i'm dealing with 
more complex regular expressions.

how can i get the number of mismatches. Basically the output of the program 
would tell me:
>2 mismatches found in string "tastung" at position 2 (a) and 5(u).

I have tried the iterator above but does not seem to do what i want???
std::string::const_iterator start = in.begin();
std::string::const_iterator end = in.end();
boost::sregex_token_iterator i(start, end, *regex, -1), j;
while(i != j)
{
   cout << *i << endl;
}
