Want to filter the lines formed by the 3 parts: <br />
part1 part2 part3 <br />

part1 contains alphanumeric, (), -, and _<br />
part2 and part3 are digits.<br />
For example,<br />

For only part2 and part3, it's something like<br />

how to match/filter the lines in perl

Perl is a high-level, general-purpose, interpreted, dynamic programming languages with over 25 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large-scale development projects.  Perl gained widespread popularity as a Common Gateway Interface (CGI) scripting language, in part due to its regular expression and string parsing abilities. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications.
