[jQuery] problem filtering out via parents() and :not()

[pixeline]

Hello !
I'm assigning a specific "swap position" behaviour on click to a list
of links, all sitting inside a multilevel unordered list with id
"detailsNavigation"

That behaviour only concerns specific anchors and those with class
"noSwap" shouldn't ... swap.

Can you explain me why this does not work?


 $("#detailsNavigation li ul li a").bind("click", function()
          {
                var $thisA = $(this);
                var $thisLI = $thisA.parent();
                var $thisUL = $thisLI.parent();
                if ($thisUL.parents('li').is(':not("#metadesign,
#editions, #timeline, #related")') || $thisA.is(':not(".noSwap")'))
                {
                // do that swappin' thingy
                }
});


Here is the related html:

    <ul>
        <li class="clearfix" id="metadesign">

            <ul style="display: block;" class="detailsSubnav clearfix
selected">
                <li class="clearfix" style="width: 100%;">
                    <ul class="metaSection clearfix">
                        <li class="skinColor
metaSectionTitle">concepts</li>
                        <li><a class="ajax noSwap" href="http://m2.lab-
au.com/projects/f551/metadesign/concepts/8/">
                            electrosensing</a></li>
                    </ul>
                    <ul class="metaSection clearfix">
                        <li style="display: list-item;">
                         <a class="ajax selected noSwap" href="http://
m2.lab-au.com/projects/f551/metadesign/methods/
referencing/">referencing</a>
                        </li>
                        <li class="skinColor
metaSectionTitle">methods</li>
                        <li class="inactive"><span
class="inactive">Data mining</span></li>
                    </ul>
                </li>
            </ul>
        </li>
    </ul>

Thanks a lot for your help!
