s.reserve(is.rdbuf()->in_avail());
char c;
while(is.get(c))

if(s.capacity() == s.size())
s.reserve(s.capacity() * 3);
s.append(1, c);
}
}
int main(int argc, char** argv)
{
std::string s;
int i;
// argc = 2;
// argv[1] = "C:/schmidt23_cpp/example/debug/bookmark.htm";
for(i = 1; i < argc; ++i)
{
std::cout << "Findings URL's in " << argv[i] << ":" << std::endl;
s.erase();
std::ifstream is(argv[i]);
load_file(s, is);
is.close();
boost::sregex_token_iterator i(s.begin(), s.end(), e, 1);
boost::sregex_token_iterator j;
while(i != j)
{
std::cout << *i++ << std::endl;
}
}
return 0;
}
i need to know how to "get/fetch" the output - currently to console, into a
field in order to continue it's processing?
thanks meir
