Question

I want to remove a word from a string if it contains 3 or more consecutive numbers and it is the first word in the string?

I think i will need the replaceFirst() function but i am not sure about the regex

eg.

Hello world one two. –> no change

H931llo world one two. –> world one two.

Hello world 112 one two –> no change

edit: consecutive numbers

Answer 1

The following regex will only match words at the beginning of the string if that word contains at least three consecutive digits:

^\w*\d{3}\w*

\w matches [a-zA-Z0-9_], and usually letters from other languages if a Unicode option is enabled.
