I try to access and use different pages in NCBI such as  

<http://www.ncbi.nlm.nih.gov/nuccore/NM_000036>
However, when I used perl's LWP::Simple 'get' function, I do not get the same output I get when I save the page manually (with the firefox browser 'save as html' option). What I do get from the 'get' function lacks the data I require.

Am I doing something wrong?
Should I use another tool? 

My script is :

```
use strict;
use warnings;
use LWP::Simple;

my $input_name='GENES.txt';

open (INPUT, $input_name ) || die "unable to open $input_name";
open (OUTPUT,'>', 'Selected_Genes')|| die;

my $line;

while ($line = <INPUT>)
{

    chomp $line;
    print OUTPUT '>'.$line."\n";
    my $URL='http://www.ncbi.nlm.nih.gov/nuccore/'.$line;
#e.g:
#$URL=http://www.ncbi.nlm.nih.gov/nuccore/NM_000036

    my $text=gets($URL);
    print $text."\n";   
    $text=~m!\r?\n\r?\s+\/translation="((?:(?:[^"])\r?\n?\r?)*)"!;
    print OUTPUT $1."\n";

}

```

Thanks in advance!
