regex - How to match emoticons with regular expressions?

Question

I need to capture smiley faces like

:)
:P
:-P
=)
:D
;)

And so on, along with general text. This is my current regex:

[0-9A-Za-z'&-./()=:;]+

However, it doesn't match ()=:; for some reason. Am I missing something?

Edit: Based on Mark's feedback here is an example that I need to parse:

hi =as.) friend :) haha yay! ;) =) test test) R&R I.O.U. 24/7

This should extract:

hi
friend
:)
haha
yay
;)
=)
test
test
R&R
I.O.U.
24/7

I'm having trouble getting this to work using any of the solutions proposed.

Answer 1

This is an example that captures a word followed by the above examples. It captures a single word and a following emoticon in separate capture groups. The Rubular link.

s(w+)s((?::|;|=)(?:-)?(?:)|D|P))

Edit Based on the edits and the given example, this might be what is desired. It defines two capture groups, one for the general text and one for an emoticon. Here is the Rubular link.

([0-9A-Za-z'&-./()=:;]+)|((?::|;|=)(?:-)?(?:)|D|P))
