issue to detect first matching end of string with regex

Question

I try to find the string starting with "start" and ending with one of this strings: (, |. | finish) with skipping "finish" when its followed by a "not" or "here".

Here is the example:

CONF: For this charaxter start 6 years of  this Revision 01 its indicated in the house warranty  not finish for  received days  completion. affected you. of your face

for this i used the following regex:

(start|START).*(?!not finish|here)(?=[.]|[,]|finish)

link for my try: https://regex101.com/r/USaH6I/1

requested return is:

start 6 years of  this Revision 01 its indicated in the house warranty  not finish for  received days completion

but I got:

start 6 years of  this Revision 01 its indicated in the house warranty  not finish for  received days completion, affected you

Answer 1

If you meant skipping matching if 'here' or 'not' is found after 'finish' then try this: (?:start|START).*?(?=[.]|[,]|(finish (?!here|not)))

If you meant skipping matching if 'here' or 'not' is found before 'finish' then try this: (?:start|START).*?(?=[.]|[,]|((?<!here|not) finish))

These follow your condition of stopping when, or. is found.

Cases:

When 'finish' is found first:

CONF: For this charaxter start 6 years of this Revision 01 its indicated in the house warranty not finish for received days finish here completion. affected you. of your face

When 'finish' if followed by 'here'/'not' it will skip till a , or . is found:

CONF: For this charaxter start 6 years of this Revision 01 its indicated in the house warranty not for received days finish here completion . affected you. of your face

CONF: For this charaxter start 6 years of this Revision 01 its indicated in the house warranty finish not for , received days here completion. affected you. of your face
