If that's the case, I think everything you need is in the libwww-perl bundle from CPAN. First, take a look at the HTML source for the form. Make yourself an LWP::UserAgent, put together an HTTP::Request with the URL from the form's action parameter and the appropriate content for the form's fields. CGI.pm can help you properly encode your form data. Grab the text you want from the response (HTTP::Response), and save it off to a file. Loop over a data file containing the data you want to process, appending each response to your output file.

You can use LWP::UserAgent; to mimic the POST as if it came from filling out the form. The returned page can be appended to a file with open FH,">> eventual.txt"; print FH; (assuming data in $_). Lather, rinse, and repeat.

Update: Extending remarks in response to jettero. '$ man LWP::UserAgent' will get you started. 'apropos LWP' will tell you where to find more. The HTTP:Request module (basic to using LWP::UserAgent) also has a man page. To see what gets sent by the browser, modify the action in the form to read 'mailto:me@localhost' or whatever. You will see that POST consists of 'key=value' pairs, too, but in content rather than as URI modifiers.

Just how do you get LWP::UserAgent to mimic the POST?

try something like this (from perldoc lwpcook):

use HTTP::Request::Common qw(POST);
use LWP::UserAgent;
$ua = LWP::UserAgent->new;

my $req = POST 'http://www.perl.com/cgi-bin/BugGlimpse',
        [ search => 'www', errors => 0 ];

print $ua->request($req)->as_string;
