I would like to get the userIds only as below:

I've used ^(?:[^,\r\n]*,){3}([^,\r\n]+).* but it gets me "Usernames", I want is Userids.

I wish somebody who can help me to find the right Regex to extract the userids only.

Thank you

回答1:

Use the advantage the time in the AM/PM format is present before each ID as well as the ID is surrounded with " characters:

(?:AM|PM),=\"(\d+)\"

Check the demo at Regex101.

回答2:

You could use Match the =" and repeat the group 2 times instead of 3. Then capture 1+ digits.

Note to repeat the character class [^,\r\n] using * for 0 or more times.

If you want the digits only, you could replace with group 1 using $1

^(?:[^,\r\n]*,){2}="(\d+)".*

^ Start of string
(?:[^,\r\n]*,){2} Repeat 2 times matching 0 or more times any char except a comma or a newline, then match ,
=" Match literally
(\d+) Capture group 1, match 1+ digits
".* Match " and match the rest of the line

Regex demo

If you want the match only, you could make use of \K to reset the match buffer, then match the digits and assert a double quote on the right.

^(?:[^,\r\n]*,){2}="\K\d+(?=")
