I'm afraid you will need file parsing, it is not that simple.

To "erase" the contents of a file before writing new content, open the file with the trunc filestream mode:

#include <fstream>

int main ()
{
   std::ofstream ofs("test.txt", std::ofstream::trunc);

   ofs << "lorem ipsum";

   ofs.close();
}
