Regex to trim hyphens from start and end of a string

Question

What's a regex pattern to trim the hyphens from the start and end of a string?

-----name1-name2----- 

should become

name1-name2

^(-+).+(-+)$ doesn't seem to work...

Answer 1

I would take the opposite approach, and pull the middle out like this:

^-+(.+?)-+$

Answer 2

You need to match either the beginning or the end like this:

(^-+)|(-+$)

If I try this out in PowerShell I get the following result:

PS> "-----name1-name2----" -replace "(^-+)|(-+$)", ""
name1-name2
