QDomNode replaceChild is not work

[lucasbemo]

Hi,

I'm trying to use the code below, but I have not had success. Could anyone help me?
NewCode this object always null. : /

QDomNode *oldNode = &this->documento.childNodes().at(2).childNodes().at(4).childNodes().at(0).childNodes().at(indiceLinhaAtual);
                QDomNode newNode = this->documento.childNodes().at(2).childNodes().at(4).childNodes().at(0).replaceChild( nodeAux, *oldNode);

QDomNode *oldNode = &this->documento.childNodes().at(2).childNodes().at(4).childNodes().at(0).childNodes().at(indiceLinhaAtual);
                QDomNode newNode = this->documento.childNodes().at(2).childNodes().at(4).childNodes().at(0).replaceChild( nodeAux, *oldNode);

To copy to clipboard, switch view to plain text mode

Eh, what is the exact purpose of that piece of code?

Never mind. QDomNode is explicitly shared. You don't need the pointer semantics:

QDomNode oldNode = this->documento.childNodes().at(2).childNodes().at(4).childNodes().at(0).childNodes().at(indiceLinhaAtual );
QDomNode newNode = this->documento.childNodes().at(2).childNodes().at(4).childNodes().at(0).replaceChild( nodeAux, oldNode);

QDomNode oldNode = this->documento.childNodes().at(2).childNodes().at(4).childNodes().at(0).childNodes().at(indiceLinhaAtual );
QDomNode newNode = this->documento.childNodes().at(2).childNodes().at(4).childNodes().at(0).replaceChild( nodeAux, oldNode);

To copy to clipboard, switch view to plain text mode 

Try that first. If that doesn't do what you want it to do, then explain here.

And read through the QDomNode docs carefully (including the class description).
