QXML - Are children accessed sequentialy

I have, lets say, the following XML:

<geometry>
    <point x=0 y=0/.
    <point x=1 y=1/.
    <point x=2 y=2/.
</geometry>

And I have the following code:

QFile file(...);
QDomDocument dom;
dom.setContent(&file);
QDomElement geometry = dom.documentElement();
for( int i=0; i<geometry.childNodes().size(); ++i ) {
    std::cout << childNodes().item(i).toElement().attribute("x").toDouble() << std::endl;
}

Is it guaranted that my output will always be that below?

1.0
2.0
3.0
Solution

  • Yes, it is, because QDomNodeList returned by childNodes implements W3C's NodeList which is ordered.
