Weird break which breaks my design

Hey,

like the headline says, I have a weird <br=” “> in my code.

<li class="tfk_col1 tfk_avatar_48" <br=""> title= .........

or like this

<li class="tfk_desc">
<a <br="" href="/aufgaben/?mode=projects&filter_project=0&proj=1&view=1#tfk_task_title">
title="Title".....

How can I clean this?
