如何使用 QXmlStreamReader 读取 XML 中具有相同标签“JobName”的元素

Answer 1

QFile* file = new QFile(paths);

if(!file->open(QIODevice::ReadOnly | QIODevice::Text)){
    qDebug() << "Failed To Open Xml";
    return;
}

QXmlStreamReader* xml = new QXmlStreamReader(file);

while(!xml->atEnd()){

    QXmlStreamReader::TokenType token = xml->readNext();

    if(token == QXmlStreamReader::StartDocument){
        continue;
    }

    if(xml->name() == "JobName"){
          qDebug() << xml->readElementText();
    }
}
