I tried using www:Mechanize to do it (after searching the web). What i have so far is:
my $ua = LWP::UserAgent->new;
$ua->env_proxy;
$te='hallo hallo hallo';
print $te;
my $response = $ua->get('http://sentimentanalyzer.appspot.com','in
+put'=>$te);
if ($response->is_success) {
#In here i want to retrieve a value from the site after
# inserting the text and hitting the "submit" button.
}
The textarea in the site is named "input".
I also didn't figure out how to activate the button..
