QDomNode Swap

[shahriar25]

Hi
How can I swap two nodes in a QDomDocument (xml) ?

As QDomDocument doesn't provide a swap() method itself you might just do it the oldschool way (untested):

QDomDocument a, b;

// Swap QDomDocuments
{
   QDomDocument tmp(a);
   a = b;
   b = tmp;
}
This works because `QDomDocument` implements the `operator=`.

There are also other ways and maybe somebody has a better solution. Maybe you can even use `std::swap`.

If you have a pointer to both QDomNode, you can use
