如何在Qt中解析XML字符串

#include <QCoreApplication>
#include <QDebug>
#include <QDomDocument>
#include <QString>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QString xmlString = R"(
        <root>
            <item id="1">
                <name>Item 1</name>
               <value>Value 1</value>
            </item>
            <item id="2">
                <name>Item 2</name>
               <value>Value 2</value>
            </item>
        </root>
    )";

    QDomDocument doc;
    if (!doc.setContent(xmlString)) {
        qDebug() << "Failed to parse XML string";
        return 1;
    }

    QDomElement root = doc.documentElement();
    QDomNodeList items = root.elementsByTagName("item");
    for (int i = 0; i< items.count(); ++i) {
        QDomElement item = items.at(i).toElement();
        int id = item.attribute("id").toInt();
        QString name = item.firstChildElement("name").text();
        QString value = item.firstChildElement("value").text();
        qDebug() << "Item" << id << ":"<< name << "="<< value;
    }

    return 0;
}
