Yet another Regexp question

[HaggMan]

I'm trying to get the regular expression which matches text between two
underscores:
_MATCHTHIS_

The problem is, I don't want to match it if the only thing in between
the underscores are spaces or other underscores:
_ _ _
(this should get no match)

_hello world_
(this should match "hello world" even though there's a space because
there's also things besides a space and underscore)

Right now, I've got this:
/_([^_]+?)_/ which does well at excluding _

I've also tried this:
/_([^_\s]+?)_/ which does well if there are NO spaces between the _'s.
ie:
_hello_
(correctly matches "hello")
_hello world_
(does not match "hello world" as I would like)
_ _ _
(correctly does not match this)

I'm stumped. Any help?

Is _hello_world_ a match or not? The following pattern might be what
you need:

/\b_\B(.+?)\B_\b/

Boundary conditions are used here instead of conditions on what's
inside.

Thank you to both of you! I'll try them out tonight.

_hello_world_ should match "hello" but not "world_" though it should
technically *never be used that way in what I'm doing.

Then my pattern won't work.

[HaggMan]

Well, Rik's worked. Thank you both!
