Trying to build a regex to verify a string that would look something like this
#tag #tag2 #tag3 and not like this #tag1 tag2 tag3
I need a regex that will make sure that the first character after a space in the string is a #.
I have the check to make sure the first character is a # but that is as far as I have been able to get on this.
pattern: /^\#/

You may use this regex:
^#[^#\s]*(?:\s#[^#\s]*)*$
RegEx Breakup:
^: Start#: Match a#[^#\s]*: Match 0 or more of any characters that are not#and not a whitespace(?:: Start non-capture group\s: Match a whitespace#: Match a#[^#\s]*: Match 0 or more of any characters that are not#and not a whitespace
)*: End non-capture group$: End
