I have a string
[ 14.21 | | Pobiedziska Letnisko 2 11.16 | 1 ]
I need a value between second "|" character and number "2" or "1"
Only this part of string without the "|" character and without the number.
I was trying this pattern
(?<=\|).+?(?=(1|2))
But as you can see, this pattern is not good as the match started with the first character "|" and I need to do it from the second "|" character.
>Solution :
You could use a capture group starting after the second pipe char matching till the first occurrence of 1 or 2.
Note that .+? can also match | so it will cross the | if the 1 or 2 is after a pipe char at the right.
^[^|]*\|[^|]*\|(.+?)\b[21]\b
If you don’t want to cross newlines or pipe chars, you can extend the negated character class like ^[^|\r\n]*
Another option using lookarounds as in your question with a negated character class not crossing a pipe char:
(?<=^[^|]*\|[^|]*\|)[^|]+(?=\b[21]\b)
(?<=^[^|]*\|[^|]*\|)Assert 2 pipe chars to the left of the current position[^|]+Match any character except|(?=\b[21]\b)Postive lookahead, assert 2 or 1 to the right
