if there is a class called An and there are many classes with class An on the page, how do you find out the An other than the current A?
<ul>
    <li class="A">
        <ul>
            <li class="A">
                
            </li>
            <li class="A">
                <ul>
                    <li class="A">
                        
                    </li>
                </ul>
            </li>
        </ul>
    </li>
    <li class="A" >
        
    </li>
</ul>
how do I find all An except the current element?
