Read Write XML File In C++

I researched a lot on how to read and write ( update ) a simple .xml file in C++ but i am not able to develop the code for it.

I work and installed xerces-c library that I think is needed to use DOM or SAX2 parser to read it.

Please someone can help to write the code for it.

A sample code to do this will be quite helpful.

Thanks & best Regards, Adarsh Sharma
