I have a specific format data as shown below in notepad++, i would like to remove lines having textual data like "This is first sentence".
1.(AB123456)
2.This is first sentence
3.(AD2341278)
4.tHIS is second sentence
5.(ABCD1234)
6.4 (four) is a number
One hint is all the lines that i need have a bracket "(" , however in textual data there are brackets too.
I tried using other means like number of letters (5 or more letters, since there are maximum 4 letters even in one i need to retain)like in regex (.*[A-Za-z]){5,} , however it did not help me to delete the entire line.
Can anyone help me with simple regex solution to remove lines?
notepad++ looks like this
Desired output should look like this
>Solution :
Case 1: Matching lines like (AB123456)
You can try chaining your match to spaces + end of line character [\s]*($|\n) and retrieve all alphanumeric characters between parentheses \([\w]+\).
\([\w]+\)[\s]*($|\n)
Case 2: Matching lines like This is first sentence
You can try chaining your match to the start of line character (\n|^), catch the first character as a non opened parenthesis ‘[^(]’, then match everything else on the same line .*.
(^|\n)[^\(].*
