( #3333=superdoc: print w/ replies, xml ) Need Help??

One way around the limitation would be to store your array values as joined strings:
That works for simple strings, but once you get to more diverse strings, you should probably consider a serializer. I find that JSON::XS works great for this purpose, as does Data::Dumper with an eval. The latter method may not always be the best choice, though. JSON is more portable and can be read by another non-Perl application more easily.
For example:

# Using JSON::XS use strict; use warnings; use DB_File; use JSON::XS qw( encode_json ); my %hash; unlink "tempfile"; #Remove previous file, if any tie %hash, "DB_File", "tempfile", O_RDWR | O_CREAT, 0666, $DB_HASH or die "Cannot open file 'tempfile': $!\n"; while ( $sourceString =~ /example(key)regex(value)example\b/ig ) { my $key = $1; my $value = $2; my $string_to_insert = encode_json( [ $key, $value ] ); push( @{ $hash{$key} }, $string_to_insert ); #Push the value in +to the hash } #And then use decode_json() from JSON::XS somewhere else to get an arr +ay of your values.
