    ''below program is in console application''

    #include <QtCore>
    #include <QtXml>
    #include <QDebug>

    void listelements(QDomElement root,QString tagname,QString atttr)
    {

    QDomNodeList items=root.elementsByTagName(tagname);

    qDebug()<<"total items="<<items.count();

    for(int i=0;i<items.count();i++)
    {
    QDomNode itemnode=items.at(i);
    if(itemnode.isElement())
    {
    QDomElement itemle=itemnode.toElement();

    	qDebug()<<itemle.attribute(atttr);
    }
    

    }
    }

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

    QFile file("C:/Users/Administrator/Desktop/siva.xml");
    if(!file.open(QIODevice::ReadOnly|QIODevice::Text))
    {
    qDebug() << "failed to open";
    return -1;
    }
    else
    {
    if(!document.setContent(&file))
    {
    qDebug() << "failed to load";
    return -1;
    }
    file.close();
    }
    QDomElement root=document.firstChildElement();
    listelements(root,"Book","Name");

    qDebug()<<"\r\n more\r\n";

    QDomNodeList books=root.elementsByTagName("Book");
    for(int i=0;i<books.count();i++)
    {
    QDomNode booknode=books.at(i);
    if(booknode.isElement())
    {
    QDomElement book=booknode.toElement();
    qDebug()<<"chapters"<<book.attribute("Name");
    listelements(book,"chapter","Name");
    }
    }

    qDebug() << "finished";

    return a.exec();
    }

    @siva9111 Come on - this is really not that hard. You just need to pass the URL to your file to QTextBrowser::setSource and it will load the content of your XML file...
    To get the URL to your file use https://doc.qt.io/qt-5/qurl.html#fromLocalFile

        @siva9111 said in xml file:

        XML files are text files, they should load same way other files do.
        Please show the code where you load the XML file in your text browser.

          this is working :
          QUrl url=QUrl::fromLocalFile("C:/Users/Administrator/Desktop/siva.txt");
          ui.textBrowser->setSource(url);

          this not loading:
          QUrl url=QUrl::fromLocalFile("C:/Users/Administrator/Desktop/xmlinfo.xml");
          ui.textBrowser->setSource(url);

            @siva9111 said in xml file:

            C:/Users/Administrator/Desktop/xmlinfo.xml

            Does this file exist?
            What does url.isValid() return?

                    @siva9111 Does it work if you use https://doc.qt.io/qt-5/qtextedit.html#setPlainText instead of setSource?
