Regular Expression for text in between tags

Question

I have a QString that I need to parse. This QString is a QNetworkReply object obtained from an URL.

        <label id='Today_LastSale1'>$&nbsp;21.2401</label>

I need the value 21.2401 from the QString.

I am tried this.

       QRegExp rx("<label id='Today_LastSale1'>$&nbsp;(\\d)</label>");

But it returns -1. Need help with this.

Thanks in Advance!
