How to have Regular expression keep first 14 characters and start changes at character 15 or beyond

I need a regular expression that keeps the first 14 characters of a string intact with no changes.  However, if there is a hypen in character 15 or beyond, remove the hypen and all text past the hypen.  If the string is 14 characters or less, do nothing.
Any help on this is greatly appreciated.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

just get the first group of this regular expression:


You can test it in this amazing tool:
This will only keep the first 14 characters if there is a hyphen beyond that point.

This will keep the first 14 characters and anything up to but not including the hyphen.
