How can I make a QString html-escaped

Question

How do I escape/sanitize a QString that contains HTML?

I.e. showInBroswser(escaped(str)) == showInNotepad(str);

Answer 1

Qt 5

Use QString::toHtmlEscaped()

QString src;
Qstring html = src.toHtmlEscaped();
showInBrowser(html) == showInNotepad(str);

QString src;
Qstring html = Qt::escape(src);
showInBrowser(html) == showInNotepad(str);
