[jQuery] a:not named anchor

Hi,
I have a relatively simple question that I have been working on. I
would like exclude all anchors that point to named anchors within a
given page from a particular function. What's the simplest way to
express this?
Anchors that don't have "#" as the first character in their
reference..
$("a:not "#" as the first character in their href").someaction
Any ideas?
Thanks much,
Nikola
