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);

Qt 4

Use Qt::escape.

#include <QtGui/qtextdocument.h>  QString src; Qstring html = Qt::escape(src); showInBrowser(html) == showInNotepad(str);
