Question

I have this regular expression:

var from = result.match(/^From\:(.*)/m)[1].replace(/^\s+/, '');

The problem is that I have 2 “From:” and I want to get both. How do I get the next “From:” ?

Answer 1

You can do it in one statement with a lookbehind (?<=) which matches, but doesn’t capture

var from = result.replace(/(?<=^From\:)\s+/mg, ”);

Edit: javascript doesn’t support lookbehinds, so you need to do this:

from = result.replace(/^(?:(From\:)\s+|.*)/mg,"$1")
