How to create a regex that will match an arbitrary sequence of spaces and tabs

Question

Could anyone help me to assemble a pattern that matches an arbitrary sequence of spaces and tabs?

Answer 1

[ \t]+

will match arbitrary sequences (e.g., spaces followed by tabs followed by more spaces ...).

Answer 2

( |\t)+ will match a sequence of one or more spaces or tabs, is that what you're looking for ?

Answer 3

To piggy-back on @Justin Morgan's answer, note that according to https://regex101.com/, \s+ is equal to [\r\n\t\f\v ]+.

Therefore, if your system doesn't support the \s+ (or \s*) construct, use [\r\n\t\f\v ] in place of the \s part instead.

Answer 4

\s+ should capture all whitespace, including spaces, tabs, carriage returns, and some weird whitespace characters. Use \s* if you want it to be optional.
