How to replace all BUT the first occurrence of a pattern in string

Question

quick question: my pattern is an svg string and it looks like l 5 0 l 0 10 l -5 0 l 0 -10 To do some unittest comparison against a reference I need to ditch all

Answer 1

I found this solution at https://www.regextester.com/99881, using a lookbehind pattern:

/(?<=(.*l.*))l/g

Or more generally

/(?<=(.*MYSTRING.*))MYSTRING/g

where MYSTRING is something that you want to remove.

(This may also be a useful string for removing all but the first occurrence of "Re:" in an email subject string, by the way.)
