Two words separated by a space followed by a comma more than one time

Question

I want to create a Regex that separates any number of words by semi-colons. For example:

word1 word2;word3 word4;word5 word6....

Here's what I've tried:

^.*(;){0,}

But this allows using more than one semi-colon side by side.

Answer 1

Based on your comment, you need an expression that matches a string of words separated by either a semicolon, a space, or both.

^(\\w+( ;?|; ?))+\\w+$

Explanation:

^           | Enforce beginning of string
(           | Group the following:
  \w+       |   One or more consecutive word characters
  ( ;?|; ?) |   A space, semicolon, or combination of the two
)+          | End group; match one or more of them
\w+         | One or more consecutive word characters
$           | Enforce end of string
