QDomNode

Hi,
I am using QT4.3. I have no idea about how can i use a QDomNode in my project. When I declare a variable like this
QDomNode vconfig;

and try to make the program, then qt display some errors like this.

Only modules QtCore and QtGui are enabled by default. To link against the QtXml module, add this line to your qmake .pro file:
