RegEx for no whitespace at the beginning and end

Question

I want to design an expression for not allowing whitespace at the beginning and at the end of a string, but allowing in the middle of the string.

The regex I\'ve tri

Answer 1

I found a reliable way to do this is just to specify what you do want to allow for the first character and check the other characters as normal e.g. in JavaScript:

RegExp("^[a-zA-Z][a-zA-Z- ]*$")

So that expression accepts only a single letter at the start, and then any number of letters, hyphens or spaces thereafter.
