Perl and OPACs

hello to everybody

the question is (maybe) not difficult but it may employ long time to resolve.

please go to

this is the on line catalogue of a university (sorry for the italian language) made with ALEPH. You can find other info and english demos about this software at:

all that I want is a dynamic perl page that passes to the catalogue some string search (IE a perl page that automatically finds all the books that have the word "mathematics" on the title) and returns a list of the matching headers

in other words something like "click here to find all the mathematics books of the university" with "here" hyperlinked to the perl page in question.

I think that the difficult is on the large use of dynamic session-ids inside this software.
bye and thanks

#! /usr/bin/perl
use CGI;
use HTTP::Request;
use LWP::UserAgent;
$::query = new CGI;
$url = "http://your-URL-here";
$usr = LWP::UserAgent->new();
$req = HTTP::Request->new(GET=>"$url");
$txt = $usr->request($req);
undef $/;
$x = $_= $txt->content();
$sessionid =~s/(regular-expression-to fetch-sessionid)/$1/;
# no you need to put $sessionid to $url like
$url .= "?sessionid=$sessionid";
$req = HTTP::Request->new(GET=>"$url");
print $usr->request($req);
exit 0;
# very basic script, to be improved in many ways

could you please post the code which needs to be changed

I know that this is an ORACLE solution, but I've not an administrative access to the server and I don't know the
database structure, so I must work only with the (dynamic) HTML interface.
I've thought to the following scenario:

1) with a first interrogation to the html interface the script fetch the session ID(s)

2) with a "second passage" the script builds the right url for the search.

please note that you can "fix" the search to a pre-defined search term: I.E.

<a href="">math books</a>

where is the page I desired...

the script should be build from scratch: if this is difficult I can increase the points.



If you want to know how to use patterns,
You will get links to perlre and perlre tutorial.

I could not open the english site :( and I dont understand
 italian :(

Well, where is the data lying? Is it in oracle or it is coming from HTML form?

If the data is lying in Orcale, then I think you need to know database structure.

Do you know how to connect to oracle using perl?

Also to read database and knowing a database structure does not need administrator access.
