It is not enough to use ForceArray in this case, because the XML that the OP presents uses
key attributes. The regular elements will be forced into an array structure but the key attributes would still live in an unsorted hash.
The solution is to combine ForceArray with the option KeyAttr to also force key attributes into an array.
my $config = XMLin("meep.xlf", ForceArray => 1, KeyAttr =>[]);
NB: This changes the structure that XML::Simple returns so you will need to update your code a little.
I tend to use Data::Dumper to inspect the hash that XML::Simple returns to check if that meets my needs.
