John,
If you say jQuery doesn't support the OR selector '|', then I'm
confused. I have a form with one SELECT element and several INPUTs.
Check out the following results from Firebug:
>>> $('INPUT', $('#myform')).length
6
>>> $('INPUT|SELECT', $('#myform')).length
7
That's what I expected as a result.. can you explain?

Subject: Re: [jQuery] Form plugin's serialize(): performance issues
Unfortunately, jQuery doesn't support the OR selector '|', otherwise
that'd work quite nicely. The problem is that I don't know how this
would work without using "*", and filtering away what you don't need -
while still keeping the order of all the elements that you want.
If anyone has any ideas, I'm all ears.
