Joey: Package identifier: (\S+) selects the whole line, (?<=Package identifier:) (\S+) helped me Thanks. Also please tell me what is \S here?

\S matches a non-space character.

Abhishek: That's why there are parentheses around it, so you have that in a group. If you use the lookbehind you should include the space in it as well, so that you can use the whole match.

I will tell you, but only because you finally got the slashes’ slope correct. :)

 /Package identifier: *([^\n]*)/

Now the ID is in the first capture group. Omit the slashes if your regex engine doesn’t need delimiters like that.

@Abhisek: Then you misrepresented the input file.
