本程序已經極度精簡了，

運行截圖如下：

代碼如下：

#include <QApplication> #include <QXmlStreamWriter> #include <QDebug> #include <QFile>int main(int argc, char *argv[]) {QApplication a(argc, argv);QFile file("my.xml");if (!file.open(QFile::ReadWrite|QIODevice::Truncate)){qDebug() << "Error: cannot open file";return 1;}QXmlStreamWriter stream(&file);stream.setAutoFormatting(true);stream.writeStartDocument();stream.writeStartElement("最外層");stream.writeTextElement("結點一", "哆啦A夢");stream.writeTextElement("結點二", "蠟筆小新");//第一個stream.writeStartElement("內一層");stream.writeTextElement("姓名", "球球");stream.writeTextElement("照片文件", "C:\\xxx.txt");stream.writeTextElement("家庭關系文件", "C:\\xxx.data");stream.writeTextElement("是否有寵物","有個雞兒");stream.writeTextElement("月工資","13999");stream.writeTextElement("有幾個男朋友","1");stream.writeStartElement("車有幾個輪子");stream.writeAttribute("include", "1");stream.writeTextElement("前男友文件", "C:\\xxxx.xml");stream.writeEndElement();stream.writeEndElement();//第二個stream.writeStartElement("內一層");stream.writeTextElement("姓名", "球球");stream.writeTextElement("照片文件", "C:\\xxx.txt");stream.writeTextElement("家庭關系文件", "C:\\xxx.data");stream.writeTextElement("是否有寵物","有個雞兒");stream.writeTextElement("月工資","13999");stream.writeTextElement("有幾個男朋友","1");stream.writeStartElement("車有幾個輪子");stream.writeAttribute("include", "1");stream.writeTextElement("前男友文件", "C:\\xxxx.xml");stream.writeEndElement();stream.writeEndElement();stream.writeEndDocument();file.close();qDebug() << "write finished!";return a.exec(); }
