Hello Mr. Muskrat and thanks for your reply.

I didn't have the code that I tried and I tried so many things that I decided to start from scratch... ;-)

Anyway I have tried your answer and first of all, it doesn't really answer the question because I was asking about selectively extract from one Zip and copy the files into another Zip. Which mean that I do not know yet what the file list is.

Based on your example and trying to remember what I did before, here is the code that I came up with:

use strict;
use Archive::Zip qw( :ERROR_CODES :CONSTANTS );

my $oldfile = 'oldzip.zip';
my $newfile = 'newzip.zip';

my $oldzip = Archive::Zip->new();
$oldzip->read($oldfile) == AZ_OK or die 'read error';

my $newzip = Archive::Zip->new();

# Getting the list of selected files
my @FileMembers123 = $oldzip->membersMatching("123.*\.xml");

foreach my $file (@FileMembers123)
{
    $oldzip->extractMember($file);
    $newzip->addFile($file);
}

$newzip->writeToFileNamed( $newfile ) == AZ_OK or die 'error somewhere
+';

When I try to execute this code, I have this error message:

When I try to print the content of the array @FileMembers123, this is what I get:

Archive::Zip::ZipFileMember=HASH(0x2f122f4)
Archive::Zip::ZipFileMember=HASH(0x2f124c4)
Archive::Zip::ZipFileMember=HASH(0x2f12694)
Archive::Zip::ZipFileMember=HASH(0x2f12864)
Archive::Zip::ZipFileMember=HASH(0x2f25a2c)
Archive::Zip::ZipFileMember=HASH(0x2f2a804)
etc...

It seems that I cannot get the file names using the command my @FileMembers123 = $oldzip->membersMatching("123.*\.xml");.

If I could generate the list of the files (using a matching pattern) in my old Zip without unzipping it, it would probably work.

Thanks again!
