[jQuery] :contains ... troubling behavior


Hi there,
I am troubled by the behavior of the :contains filter
I have an a tag
<a class="undo" href="/tag/poesie/5">undo</a>
I can select it with
$("a.undo") and play with the chain not problem e.g. $
("a.undo").remove() works fine
if I use
$(':contains(<a href="/tag/sagesse/4" class="undo">undo</a>)')
or
$('a:contains(<a href="/tag/sagesse/4" class="undo">undo</a>)')
or
$('a.undo:contains(<a href="/tag/sagesse/4" class="undo">undo</a>)')
I get the "same" result "pointing" to the same tag but I can't play
with it i.e. whatever I do to it doens't have an impact on the DOM.
I am sure it is something I don't understand about JS or jQuery ...
could somebody enlighten me?
Thanks
