istream_iterator deal with string with pipe

Question

I have the following source working fine :

int main() {
    string s = "This is a book not a look " ;
    vector<string> svec;
    stringstream ss(s);
    copy(istream_iterator<string>(ss), istream_iterator<string>(), back_inserter(svec));
    for( auto it = svec.begin() ; it != svec.end() ; it++ ){
        cout << "(" << *it << ")" << endl ;
    }
} //main

Suppose I use "|" , not space in this sample , what should I modify so that it output the same result ?! I mean string s = "This|is|a|book|not|a|look" ;
