I have this type of regex
\b[0-9][0-9][0-9][0-9][0-9]\b
It’s not complete, this will match me many examples of 5 digit but I need just first and one match from this structure:
Reference Number WW
30966 CFUN22 098765334
30967 CFUN22 098765335
30968 CFUN22 098765336
30969 CFUN22 098765337
In this case I need just "30966" , not 30967,30968 and so on…
I tried to do
\b[0-9][0-9][0-9][0-9][0-9]\b
>Solution :
You can use a positive lookbehind to make sure that you’re grabbing the first 5-digit number after the word "Comments":
(?<=Comments\n)\d{5}\b
