Hello there!

I have a large Zip archive and I'm trying to extract files based on their names, and copy them into new Zip archives.

The method I'm using now is similar of what I would do using a simple batch file. First I'm extracting all the files using the ExtractTree command:

$zip->extractTree();

Then I use the "File::Find::Rule" module to add the files to new Zip archives using regular expression:

my $finder_type1 = File::Find::Rule->new()->name(qr/Type1_(.*?)\.xml$/
+i)->start(".");
while( my $file1 = $finder_type1->match()  ){
   $type1->addFile($file1);
}

my $finder_type2 = File::Find::Rule->new()->name(qr/Type2_(.*?)\.xml$/
+i)->start(".");
while( my $file2 = $finder_type2->match()  ){
   $type2->addFile($file2);
}

etc...

This is of course extremely inefficient. I tried to copy files from one Zip to another using $zip->extractMember($element) then write them to another Zip using $type1->addFile($element) but that didn't work, I got empty Zip archives as result.

I'm sure there's a way to selectively copy files from one Zip archive to another without extracting the whole thing and adding them again; is it?

Thanks in advance for help!
