Summary: regex_match problem

Initial Comment:
Ruslan Talpa <tristan_at_[hidden]>

I want to match different strings in a whois result and i 

am having some problems.

first a execut a shell command similar to:

"/usr/bin/whois domain.com > tmp_file"

so after this we have a file, from wich i read line by line 

and try to match some strings but no matter what the 

reg. expression is the regex_match returns false.

i even tried "regex expression("a");" and still no luck

The only thing i can think of is that there is some 

character encoding stuff envolved but i don't know what 

to do. Please help, tell me what i am doin wrong

here are the functions involved

int parse_line(const char*  response)

{

   regex expression("a");

   cmatch what;

   if(regex_match(response, what, expression))

   {

      cout << "MATCH\n";

   }

   else

   {

      cout << "NO MATCH\n";

   }

   return 0;

}

int get_info(string domain, char* pipe_file)

{

        string line;

        Message msg;

        strstream command;

        command << "/usr/bin/whois " << domain.c_str() 

<< " > " << pipe_file;

        system(command.str());

        ifstream f(pipe_file);

        while (!f.eof())

        {

                getline(f, line);

                parse_line(line.c_str());

        }

        f.close();

        return 0;

}
