How do I use foreach with QDomNodeList in Qt?
- by Venemo
Hi Everyone,
I'm new to Qt and I'm learning something new every day.
Currently, I'm developing a small application for my Nokia N900 in my free time.
Everything is fine, I am able to compile and run Maemo applications on the device.
I've just learned about the foreach keyword in Qt. (I know it is not in C++, so I didn't think about it until I accidentally stumbled upon a Qt doc that mentioned it.)
So, I decided to change my quite annoying and unreadable loops to foreach, but I failed with this:
QDomNodeList list = doc.lastChild().childNodes().at(1).firstChild().childNodes();
for (int x = 0; x < list.count(); x++)
{
QDomElement node = list.at(x).toElement();
// Do something with node
}
This is how I tried:
foreach (QDomElement node, doc.lastChild().childNodes().at(1).firstChild().childNodes())
{
// Do something with node
}
For some reason the above code doesn't even compile. I get cryptic error messages from the compiler.
Could someone please explain to me how to get it right?
If the foreach loop doesn't support QDomNodeList, is there a way of handling XML files that do support foreach?
