Qt工作笔记-XML文件的写入

运行截图如下：

代码如下：

#include <QCoreApplication>

#include <QFile>

#include <QXmlStreamWriter>

#include <QDebug>

int main(int argc, char *argv[])

{

    QCoreApplication a(argc, argv);

    QFile file("my.xml");

    if (!file.open(QFile::WriteOnly | QFile::Text))

    {

        qDebug() << "打开失败！";

        return -1;

    }

    QXmlStreamWriter stream(&file);

    stream.setAutoFormatting(true);

    stream.writeStartDocument();

    stream.writeStartElement("Data");

    stream.writeAttribute("subscript", "B110120119");

    stream.writeTextElement("device", "上海机器");

    stream.writeEndElement();

    stream.writeEndDocument();

    file.close();

    return a.exec();

}

此处要注意一点：
