hi ,
i have created an xml file using iostream in Qt , but i come to know we have to use xml Dom for manipulations like save, open,update and delete in the xml file .
i read the xml dom concept in C++ programming QT , but i didn't understand clearly how to create and read an xml domdocument, i am attaching xml file what i was created , please suggest me how to do this?

Thankyou
