OT - Email address stripping - Not SPAM read, and understand!

["Angel Gabriel" <angel daddyt co uk>]

I'm in a dilemma, I've received a file with a whole bunch of email address
from an electronic guestbook. It was running on the uni website, and now we
have all the email addresses, and messages and names all mixed up, and they
are not in a proper format, for instance, sometimes there is no email
address, and so when I import the thing into MS Access, it ends up with a
whole bunch of rubbish. Is there any apps out there that can strip all the
email address out of a document. I don;t mean compile a list, I mean
actually take them OUT of the document, do that the original can then be
published as a static web page?
