How to unescape XML in Qt?

Question

I have QString like "< foo & blah >" (no tags, only character data) and I want to unescape it. There is Qt::escape function in Qt 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.

It looks like someone made an html entity decoder in an answer to an old post. If you don't mind introducing a new dependency, that might be a good solution.
