Question

Hey, I can\'t figure out how to write a regular expression for my website, I would like to let the user input a list of items (tags) separated by comma or by comma and a spa

Answer 1

([^,]*)

Look For Commas within a given string, followed by separating these. in regards to the whitespace? cant you just use commas? remove whitespace?
