Qt6 QDomDocument setContent with String input error

[Bilal Can]

Hi all,

I have the code below:

    QString oXmlStream = QString("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
    QDomDocument o_dom_doc;
    QString oErrorMsg;
    int oErrLine = 0;
    int oErrCol = 0;
    if(!o_dom_doc.setContent(oXmlStream,&oErrorMsg, &oErrLine,&oErrCol))
    {
        qWarning() << oErrorMsg << " at line: " << oErrLine << " col: " << oErrCol;
        return;
    }

When I try to run this I get an error: "Premature end of document." at line: 1 col: 1

If I change the xml string like below, I get error message: unable to set content for nav mod: Expected '>' or '/', but got '[a-zA-Z]'.

QString oXmlStream = QString("<?xml version=\"1.0\" encoding=\"UTF-8\"?>") +
QString("<item name_org=\"") + QString(QApplication::translate("Navigator", "Components")) + QString("\"") +
QString("icon_path=\":/icons/components.png\"") +
QString("tab_path=\"components\"") +
QString(">") +
QString("</item>");

These codes were working in Qt5.15.14 version without giving an error, but after qt6.5.2 update it gives the error message. How can I fix the issue. The xml text is valid

Output the full string and check if the xml is valid - I would guess it's not.

I realized that there is no space between attributes inside a tag. It is interesting that old qt version does not complain about it. Thanks for the advice
