… which, since we're going through the keys in a hash, can be nicely combined with a map: 
@anArray = map { my $x; ref( $x = $xmlin->{$_} ) eq 'ARRAY' ? @$x : $x

(assuming that we want everything from the hash, not just a single entry—which is what I guess the poster wanted, which would explain the strange assignment/push choice).
