Getting the text value of all child elements

Getting the text value of all child elements

I have this html:

  1. <div id="codes">
  2. <div><a href="#"></a><span>bla</span></div>
  3. <div><a href="#"></a><span>bla2</span></div>
  4. <div><a href="#"></a><span>bla3</span></div>
  5. </div>
How can i get the value of all those child spans?

Thank you in advance.
