Dear All,

my file looks like this

ICR000010::Proteinase inhibitor I25,
--ICR001713::Proteinase inhibitor I25A, stefin A::PR00295
ICR000014::PAS::PS50112::SM00091::TIGR00229
--ICR013655::PAS fold-3::PF08448
----ICR001321::Hypoxia-inducible factor-1 alpha, PAS

NOTE :
-- means one generation
---- means second generation

OUTPUT should be

Parent is ICR000010
ICR000010 First generation child is ICR001713
Parent is ICR000014
ICR000014 First generation child is ICR013655
ICR000014 Second generation child is ICR001321

here is my CODE to write the first line

 
##!/usr/bin/perl -w

use strict;
use warnings;


open (FILE,"< C:/perl/ParentChildTreeFile.txt") or die "cannot open fi
+le for reading: $!";


while (<FILE>){
    
    if ($_ = /^(ICR\d+).*/){
                
          my $parent = $1;
          print "\n Parent is $1"; 
}
        elsif ($_ = /^--(ICR\d+).*/){
          my $firstchild = $1;
          print "\n $parent First generation child is $firstchild"; 
}
        elsif ($_ = /^----(ICR\d+).*/){
          my $secondchild = $1;
          print "\n $parent Second generation child is $secondchild"; 

}                  
}

OUTPUT :
Parent is ICR000010
Parent is ICR000014

Child Output is missing.I don't know why other if statements are not working. any help would be appreciated
