This is the tag in the HTML source:

      Web Testing  in Ruby  is fun

You can set individual options using successive _set_s and you can clear everything that is selected with the clearSelection method. The following code would select every option in the select list and then clear everything.

ie.select_list(:id, 'one').set('Web Testing')
ie.select_list(:id, 'one').set('in Ruby')
ie.select_list(:id, 'one').set('is fun')
ie.select_list(:id, 'one').clearSelection
