QDom: Edit a child node?

[nwarrenfl]

Hi.

I am developing a class that handles xml configuration files.
Now i have a function that gets an existing node and edits it, however i can't find the correct solution to get it working.

Here is my code:

void XfireGamesList::updateConfiguredGame(QString pName, QString pLaunchExe, QString pDetectExe)
{
QDomElement game = getConfiguredGame(pName);
QDomElement command = game.firstChildElement("command");
QDomElement launch = command.firstChildElement("launch");

qDebug() << launch.text();
launch.setNodeValue("somevalue");
qDebug() << launch.text();
}

getConfiguredGame() returns a QDomElement representing this node for example:

<game name="The name of a certain game">
<command>
<launch>SOME_PATH</launch>
<detect>SOME_PATH</detect>
</command>
</game>

The function isn't able to edit the node values, and the debugging calls outputs "SOME_PATH" twice, so the node should be correct since it returns the correct values, but editing fails.

Does someone know why?
Thanks in advance.

You have to modify QDomText explicit.

You have to modify QDomText explicit.

I tried this:

launch.toText().setData("somevalue");

But this didn't work either, could you explain me the correct way?

Well, that could not work...
QString xml = "<game><command><launch>SOME_PATH</launch><detect>SOME_PATH</detect></command></game>";
QDomDocument doc;
doc.setContent(xml);
QDomElement game = doc.firstChildElement("game");
QDomElement command = game.firstChildElement("command");
QDomElement launch = command.firstChildElement("launch");
qWarning() << launch.text() << launch.childNodes().count();

QDomText text = doc.createTextNode("foo");
launch.replaceChild(text, launch.firstChild());
qWarning() << launch.text() << launch.childNodes().count(); Be aware that you check if the element has a text node!
