QFile file("data.xml"); if (!file.open(QIODevice::ReadOnly)) { qDebug() << "Failed to open file for reading"; return; } QDomDocument doc; if (!doc.setContent(&file)) { qDebug() << "Failed to parse XML"; file.close(); return; } file.close();
QDomDocument doc; QDomElement root = doc.createElement("root"); doc.appendChild(root); QDomElement child = doc.createElement("child"); root.appendChild(child); QDomText text = doc.createTextNode("hello world"); child.appendChild(text);This example shows how to create a new XML document using QDomDocument, add elements to it, and write some text content to the document. Overall, QDomDocument is a powerful and flexible library for working with XML data in C++. Its intuitive API makes it easy to parse and create XML documents. It is a part of the Qt library and can be used in Qt-based applications.
