Getting and changing value in an innerHTML area

Getting and changing value in an innerHTML area

Hello,

can anyone help me i am trying to get and change a little part out of a tag-contruction, which i am not allowed to change.

   
    
    
  1. <div id="name">
    2. 
    
  2. <p><span id="nameheading">name:&nbsp;</span>Jan Jansen</p>
    3. 
    
  3. </div> 
    4.
if someone could show me how i can isolate the name ("jan jansen") only, so that i am able to replace it.

thanks for your help.
