    You need to add this to your .pro file:
    QT += xml

    Also, you can simply include QDomDocument, no need to include QtXml/QDomDocument.

    Hey mate, please don't report my posts to thank me, that has an entirely different purpose!

    If you want to thank, write a reply. If you want to do it silently, send me a private message. "report" link is there to report spammers, etc.
