Firstly this is the input file that Im reading. 
module circuit_17 (N1,N2,N3,N6,N7,N22,N23);
input N1,N2,N3,N6,N7;
output N22,N23;
wire N10,N11,N16,N19;
nand nand2_1 (N10,N1,N3);
nand nand2_2 (N11,N3,N6);
nand nand2_3 (N16,N11,N2);
nand nand2_4 (N19,N11,N7);
nand nand2_5 (N22,N10,N16);
nand nand2_6 (N23,N16,N19);
endmodule

This is a part of the code. 
    my $gate_DATA = $_;
    if (defined($gate_DATA) && ($gate_DATA =~ /(.*) (.*) \((.*),(.*),(
+.*)\);/) && ($gate_DATA !~ /module/) )    
    {
        @gate_type = $1;
        @gate_name = $2;
        @output_gate = $3;
        @input_A = $4;
        @input_B = $5;
        }

How do I store the gate data so I can access it later? By looping? For example, 
@input_A = [ N1 N3 N11 N11 N10 N16 ]

UPDATE For gate_name, I managed to capture the whole name which is nand2_1, if I want to just capture the number behind it ( meaning from nand2_1 just capture value 1) , how do I change the way to store it?
