Automating Form Submission

I used the following code as suggested in S20.2 of Perl Cookbook:

#!/usr/usc/bin/perl -w

use LWP::Simple;
use URI::URL;

my $url = url('http://164.195.100.11/netacgi/nph-Parser');
$url->query_form(TERM1 => 'alcatel',
             FIELD1 => 'ASNM',
             d => 'pt95');
unless (defined ($content = get $url)) {
    die "could not get $url\n";
}

print "$content\n";


I get back an error page:

Error #1003
<HTML>
<HEAD><TITLE>Error</TITLE></HEAD>
<BODY><H1>Error!</H1>
<HR>
<H4>BRS was unable to process your request.  A diagnostic message was mailed to the appropriate personel.</H4>
</BODY></HTML>


Where am I going wrong? By the way, this is supposed to retrieve a page from the US Patent & Trademark Office.


thanks,

You seem to be missing a bunch of hidden variables.  Try this:

use LWP::Simple;
use URI::URL;

my $url = url('http://164.195.100.11/netacgi/nph-Parser');

$url->query_form(


  Sect1 => 'PTO2',
  Sect2 => 'HITOFF',
  p => '1',
  u => '/netahtml/search-bool.html',
  r => '0',
  f => 'S',
  l => '50',
  TERM1 => 'alcatel',
  FIELD1 => 'ASNM',
  d => 'pt95'

);

print get $url;
