Here is an example which uses WWW::Mechanize to visit the page, populate the field and submit the form. Error checking is left as a exercise for you, this is a short example to get you started:

#!/usr/bin/perl

use strict;
use warnings;

use WWW::Mechanize;

my $url = 'http://www.kultusportal-bw.de/servlet/PB/menu/1188427_pfhan
+dler_yno/index.html';

my $mech = WWW::Mechanize->new();
$mech->get( $url );

$mech->field('einfache_suche','*');
$mech->submit();
# $mech->content now contains the results page.

I can't read German, so you'd better check that you're not breaking any site policy regarding automation.

I'm not an expert in robots.txt but I would understand http://www.kultusportal-bw.de/robots.txt as 'no agents allowed'.

# robots.txt von 17-8 Uhr

Update:
You can of course parse the HTML content of the search results with regex, but this is a mess...

my (@hrefs) = $mech->content =~ m|COMPLETEHREF=http://www.kultus-bw.de
+/did_abfrage/detail.php\?id=\d+|g;

print "$_\n" foreach @hrefs;    #there are 5081 of these

#these COMPLETEHREF's can be appended to a main url like this:

my $example_url = 'http://www.kultusportal-bw.de/servlet/PB/menu/11884
+27/index.html?COMPLETEHREF=http://www.kultus-bw.de/did_abfrage/detail
+.php?id=04146900';

hello Marto hello Marshall,

many thanks for the hints. I am going to make some tests with Mechanize! I make use of Mechanize instead of LWP!!

by the way:... i can read on the CPAN:
>br>
Features include:

* All HTTP methods
* High-level hyperlink and HTML form support, without having to parse HTML yourself
* SSL support
* Automatic cookies
* Custom HTTP headers


Mech supports performing a sequence of page fetches including following links and submitting forms. Each fetched page is parsed and its links and forms are extracted. A link or a form can be selected, form fields can be filled and the next page can be fetched. Mech also stores a history of the URLs you've visited, which can be queried and revisited. (end of citation)

Well - Does this mean that id do not have to do Parsing of a result-page with use HTML::TokeParser!? in other words: in the feature-list i can read: "High-level hyperlink and HTML form support, without having to parse HTML yourself" - unbelieveable!!!! Well i cannot believe this! Does this mean that i do not have to parse the fetched HTML-Pages?

Can i get the data-set of each of the 5000 Pages with Mechanize!?

Well i have to make some tests! And perhaps someone can set me straight here!!

BTW: You Marshall are right: this is a "very huge government website that performs very well." I do not think that i run into any troubles....

after the first trials i come back and report all my findings.

untill soon!!

perlbeginner!
