Hi,

I'm searching for a part of wisdom, that I was not able to find in the Internet. So it is to good hidden for me;-)

So what I'm trying to build is a perl module that does a lot of work for various perl scripts for me. However there is one little kind of code (a simple parser), that has to be provided by the calling script. So I have code like this inside the script as parser...

sub parseGroupDescription
{    my $groupObj=shift;   # my problem $groupObj is always undef / $g
+roupObj is Net::LDAP:Entry
    my $groupName=get_attribute($groupObj,"erldapservicegroup");
    my $groupDesc=get_attribute($groupObj,"description");

    my  $response;
    $response->{"name"}=$groupName;
    
    return $response;
}    # sub parseGroupDescription

I'm calling the method inside my main script using 
my $data=$zbdbObj->fetchData($ldapConn,$serviceFilter,$groupFilter,sub
+ {parseGroupDescription});

The perl module has code like 
sub fetchData
{    my $selfObj=shift;
    my $ldapConn=shift;
    my $serviceFilter=shift;
    my $groupFilter=shift;
    my $parseFunction=shift;
    
    ...
                                                            
    foreach my $group ($allGroups->entries) {
        print get_attribute($group,"erldapservicegroup")." ";
        my $response=&$parseFunction->($group);    # $group is a Net::
+LDAP:Entry object and $parseFunction a reference on the function of t
+he main script
        my $groupName=$response->{"name"};
        $serviceDataObj->{"groups"}->{$groupName}=$groupName;
    }    # foreach my $group ($allGroups->entries)
}    # sub fetchData

I could see that my parser is called within this construct, however I was not able to find a way to pass the value of $groupObj to the parser.

Any ideas?
