Single editor Multi Tag?

All,

I'm going to incorporate FCKEditor (or alternative if need be) into my clients website: The issue I have is that there a large number of "div" classes on each webpage for example:

                 <div class="block_holder_top_alt"></div>
                 <div class="content_holder_alt">
                     <h3>Is there a fee for registering as a seller?</h3>
                     <p>There is no fee for registering with XXXXX.</p>
                </div>
                 <div class="block_holder_bottom_alt"></div> 
                 
                 <div class="block_holder_top_alt"></div>

                 <div class="content_holder_alt">
                     <h3>What are the fees for selling with XXXXXX?</h3>
                     <p>There is a tiered fee schedule based on pre-determined volumes.</p>
               </div>
                 <div class="block_holder_bottom_alt"></div>
                 
                 <div class="block_holder_top_alt"></div>
                 <div class="content_holder_alt">
                     <h3>What if I already have a direct debit with XXXXXXas a buyer?</h3>

                     <p>Great! This means we will not have to set up a direct debit account, which will help speed up your registration.</p>
                </div>
                 <div class="block_holder_bottom_alt"></div> 

my understanding is that you need the FCKeditor tags for every 'div' but what I would like to know is how can we integrate/implement the FCKeditor tags (multi) but on the FRont end it appears as 1 editor - (i.e. to the user - and they can select via one editor which 'div' area to edit)
