removing text from a string

I have a string which is holding this below, is it possible to take out the url and decription inside it, so http://www.bbc.co.uk/iplayer/episode/b01gk4xc/Louis_Theroux_Louis_Theroux_Extreme_Love_Autism and Louis travels to DLC Warren in New Jersey, an innovative autism school preferably splitting them into two variables

  <p>
     <a href="http://www.bbc.co.uk/iplayer/episode/b01gk4xc/Louis_Theroux_Louis_Theroux_Extreme_Love_Autism/">
       <img src="http://node1.bbcimg.co.uk/iplayer/images/episode/b01gk4xc_150_84.jpg" alt="Louis Theroux: Louis Theroux - Extreme Love: Autism" />
