QDomElement root = xmlDoc.documentElement(); QDomNode firstChild = root.firstChild();
QDomNodeList childNodes = parent.childNodes(); QDomNode firstChild = childNodes.at(0);Here, we first retrieve the list of child nodes for a given parent node and then access the first child node using the corresponding index. Overall, QDomNode and its related classes are part of the Qt Core module and can be accessed by including the corresponding header files and linking against the Qt Core library.
