Remove spaces from the beginning and end of a string

Question

I am pretty new to regular expressions. I need to clean up a search string from spaces at the beginning and the end. Example: \" search string \" Result: \"search string\"

Answer 1

If it's only white-space, why not just use trim()?

Answer 2

Yep, you should use trim() I guess.. But if you really want that regex, here it is:

((?=^)(\s*))|((\s*)(?>$))
