      @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 not loading by QUrl

          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?
