基于 QDom

废话不多说

QString mdk_xml::xmlToQString(const QString &filename){    ret_str.clear();    QFile file(filename);    if (!file.open(QIODevice::ReadOnly))    {        QMessageBox::warning(nullptr, "Err", "Cannot open file for reading!");        return ret_str;    }    QDomDocument doc;    QString strErr;    int iErrCount;    int iErrLine;    if(!doc.setContent(&file,false,&strErr,&iErrLine,&iErrCount))    {        qDebug() << "xml err:" << strErr << "line" << iErrLine << "count" << iErrCount;        file.close();        return "err";    }    file.close();    QDomElement root = doc.documentElement();    qDebug() << root.nodeName();    xml_node(root);   return ret_str;}void mdk_xml::xml_node(QDomNode &node){    static uint8_t a=0;    static QString space="";    static uint16_t chird_index=0;    QString str;    QDomNode child;    QDomNode next;    if(a>20)//20/2=10 最多10级child    {        qDebug() << "err"<
   
    =2) a-=2;            break;        }        next = next.nextSibling();    }}
