#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();
}this is the code

@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 -
hi ,
text files are loading but xml files are not loading by QUrl -
-
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); -
-
file exist
-
@siva9111 What about my second question?
-
if(url.isValid()){
QMessageBox::information(0,"info",url.errorString());
}iam executed above code ....messagebox displayed
(due to new user iam unable to replying to you sir....its taking 10min time for next reply ...see ur inbox sir)
-
@siva9111 Does it work if you use https://doc.qt.io/qt-5/qtextedit.html#setPlainText instead of setSource?
-
does not work
