How to unescape XML in Qt?

[werkzeug]

I have \[code\]QString\[/code\] like \[code\]"< foo & blah >"\[/code\] (no tags, only character data) and I want to unescape it. There is \[code\]Qt::escape\[/code\] function in \[code\]Qt\[/code\] namespace, yet no reverse counterpart for it.So, how can I unescape XML string in Qt?Specific requirement: it must be possible with Qt 4.7.3.
