WordPress editor adding in extra tags?

Hi Guys.

The way i have the site set up is as follows, Is, it’s a one page solution, i’ve coded it in using the text editor when creating my page via the wordpress backend.

The only reason the end user needs a cms is to simply add and remove links (to Artists), the problem i’m having is the structure of my page is set up as so

<div>
link
link
link
</div>

X3 to make 3 columns of links, all works fine, However when the user adds or removes a link using the visual editor, wordpress outputs

<div>
link
link
NEWLINK</div>
<div>
link
</div>

Thus breaking the structure of my page, is there anyway i can prevent wordpress adding in these tags and literally only take the link?

Thanks
Alun
