QDomDocument doc; QDomElement root = doc.createElement("root"); doc.appendChild(root); QDomElement element = doc.createElement("child"); root.appendChild(element);
QDomDocument doc; QDomElement root = doc.createElement("root"); doc.appendChild(root); QDomElement element1 = doc.createElement("child1"); root.appendChild(element1); QDomElement element2 = doc.createElement("child2"); root.appendChild(element2); QDomElement element3 = doc.createElement("child3"); root.appendChild(element3);In this example, we create an empty QDomDocument and create a root element. We add the root element to the document using QDomDocument::appendChild(). We create three child elements and append them to the root element using QDomNode::appendChild(). The child elements are appended in the order they were created. In conclusion, QDomNode appendChild is a useful method for adding child nodes to parent nodes in an XML or HTML document. It is a part of the Qt Core library.
