Remove LI using jQuery

Advert test
I have the code below, I need to remove the opening UL and LI and the closing LI and UL and just keep the inner UL.

I've tried the everything I can think of but not being an expert in jQuery is letting me down, any help much appreciated.
      <li>item 1</li>
      <li>item 2</li>
      <li>item 3</li>
That wasn't exactly what I was looking for but I got it working after playing around with jQuery for a bit, thanks for the help though.
