HTML Question

How can I make a QString html-escaped

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

I.e.

showInBroswser(escaped(str)) == showInNotepad(str);

Answer

Qt 5

Use QString::toHtmlEscaped()

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

Reference: http://doc.qt.io/qt-5/qstring.html#toHtmlEscaped

Qt 4

Use Qt::escape.

#include <QtGui/qtextdocument.h>

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