regular expression doesn't start with character A or whitespace [closed]

Question

I want my regular expression to match strings that don't start with the letter A or whitespaces.
I've tried ^-|^(^(\W|A).), but it doesn't work, any ideas why?

Answer 1

regular expression doesn't start with character A or whitespace

^(?![A\s])

To match the whole string, you need to add .*

^(?![A\s]).*

OR

^[^A\s].*

DEMO

Strings don't start with A or Space will match also the strings starts with hyphen -, so you don't need to specify the pattern for strings starting with hyphen.

Answer 2

You were close:

^[^ A]

• [^ A] matches anything other than A or space

• ^ anchors the regex at start of the string
