Regex pattern matching issue

Question

Below is the text I am trying to match

3 INFO  ~ [com.Engine:164] italics

with

(?<=~\s\[)([a-zA-Z0-9\.]+)(?=:)(?<=:)(.*)(?=\])

I need to fetch 2 expressions out of it -

1. com.Engine
2. 164

and I do not need any more matches, not even the :.

(?<=~\s\[)([a-zA-Z0-9\.]+)(?=:)

is returning me com.Engine however the total regex doesn't give me any result.

Please help.

Answer 1

I='3 INFO  ~ [com.Engine:164] italics';
J=I.replace(/^.*?\[(.*?)\].*$/,'$1').split(':');
alert(J[0]+'\n'+J[1]);

Answer 2

How about

(?<=~\s\[)([a-zA-Z0-9\.]+):[^]]+

Answer 3

(?<=\[)[^:]+|(?<=:)[^\]]+

Try this.See demo.

Not sure about the rules for the individual parts, but how about:

.*\[(.*):(\d*)\].*
