Qt工作笔记-对QXmlStreamWriter进一步的认识（写复杂的XML文件）

本程序已经极度精简了，

运行截图如下：

代码如下：

#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("最外层");
    stream.writeTextElement("结点一", "哆啦A梦");
    stream.writeTextElement("结点二", "蜡笔小新");

    //第一个
    stream.writeStartElement("内一层");
    stream.writeTextElement("姓名", "球球");
    stream.writeTextElement("照片文件", "C:\\xxx.txt");
    stream.writeTextElement("家庭关系文件", "C:\\xxx.data");
    stream.writeTextElement("是否有宠物","有个鸡儿");
    stream.writeTextElement("月工资","13999");
    stream.writeTextElement("有几个男朋友","1");
    stream.writeStartElement("车有几个轮子");
    stream.writeAttribute("include", "1");
    stream.writeTextElement("前男友文件", "C:\\xxxx.xml");
    stream.writeEndElement();
    stream.writeEndElement();

    //第二个
    stream.writeStartElement("内一层");
    stream.writeTextElement("姓名", "球球");
    stream.writeTextElement("照片文件", "C:\\xxx.txt");
    stream.writeTextElement("家庭关系文件", "C:\\xxx.data");
    stream.writeTextElement("是否有宠物","有个鸡儿");
    stream.writeTextElement("月工资","13999");
    stream.writeTextElement("有几个男朋友","1");
    stream.writeStartElement("车有几个轮子");
    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();
}
