If you try something like:

$(this).parents(('dl:not(:last))

returns all the dl parents of this instead of all the dl parents except the last one as expected

Ricardo Tomasi said here: http://groups.google.com/group/jquery-en/browse_thread/thread/acc39ea6a0742cbe that this is an expected behavior but I don't think so because it breaks the logical behaviour (you could read my opinion in the group threat)

You could see a test case at: http://jquery.nodnod.net/cases/85 as pointed in the threat

If Ricardo Tomasi's point of view is correct in your opinion I suggest a poll request. I bet you that my opinion wins

Thanks!
