 作为记录，代码如下：

QXmlStreamReader xml(html);
    while (!xml.atEnd())
    {
        xml.readNext(); //这个是关键函数，挨个读取节点

        if (xml.isStartElement())
        {
            if (xml.name() == "ul")
            {
                while (!xml.atEnd())
                {
                    xml.readNext();
                    if (xml.isStartElement())
                    {
                        if (xml.name() == "li")
                        {
                            while (!xml.atEnd())

                                if (xml.isStartElement())
                                {
                                    if (xml.name() == "p")
                                    {
