Extract "M d, Y" formatted date expression from string

Question

My webpage looks like this

<h3>Headline</h3>

      Unimportant Nov 20, 2012<br />

I just want to get the date and format it for new DateTime.

Answer 1

([A-Za-z]{3} [012]\d, [12](\d){3})

Should do the trick. This will catch any date with the format you provided.
