I'd like to write an xml file using opencv FileStorage object.
Most of the examples I get to see works like the following
FileStorage fs("d:\\1.xml" , FileStorage::WRITE);
fs << "one" << 1;
I'd like to write a section with modified name variable , which means that the text would not have to be inserted in compile time. I look for something like this:
string st = "1";
fs << st.c_str() << 1;
However I keep on getting run time error. it's refused to work, I have tried using opencv string type, stl string type , char* , but still can't make it work.
Any help would be very appreciated
