How to convert QVariant to QDomNode

Question

I have a simple DOM model for working with XML (from this tutorial: http://doc.qt.io/qt-5/qtwidgets-itemviews-simpledommodel-example.html). Now in my code I want to get data by index like this:

auto data = model_->data(index, Qt::DisplayRole);

But method data() returns QVariant and I want to convert it to QDomNode. How can I do that? I have tried this: https://stackoverflow.com/a/24363059/5955876, but it didn't help. I guess it is because QDomNode isn't QObject. Any suggestions?

You don't need to use the data() function of our model. What you need is just extracting QDomNode object from the model index. I.e.:

[..]
QModelIndex index =  model_->index(row, column);
DomItem *item = static_cast<DomItem *>(index.internalPointer());
QDomNode node = item->node();
