my $zip = new Archive::Zip;
$zip->read('Filename.zip');
# ..obviously you have this already.

my @memberNames = $zip->memberNames;
# @memberNames is now a list of the files in the zip Archive.

Now you iterate over that array like any other array.
Is that what you wanted?

After this, of course, you can extract the files by name (using the ->extractMember method) and delete the temporary file when you're done with it.

Thank you all. I did go this route after all -

use Archive::Zip;
use Archive::Zip::MemberRead;
.....
my $zip = Archive::Zip->new($file);
my @ziplist=$zip->memberNames();
.....
foreach my $afile (@ziplist)
{
    my $member = $zip->memberNamed($afile);

    my $fh=$member->readFileHandle();
    while (my $line = $fh->getline()) {.... etc ....}

Archive::Extract may prove intersting, though you will have to extract all of the files, process and delete them.

An alternative would be to investigate somehow extracting them to memory rather than to file. You'd need to do some research on this.
