Want to filter the lines formed by the 3 parts:
part1 part2 part3
separated by spaces and tabs.
part1 contains alphanumeric, (), -, and _
part2 and part3 are digits.
A1-(ABC)XX1_(C)DE10 1223345 323242
XX10_1(2) 98765 67890
For only part2 and part3, it's something like
$_ =~ /^\d+\s+\d+$/
to filter it. How to do it if considering all 3 parts?
