You could just iterate through them:

foreach(keys %{$x->{'xylanXIPGMAPLastTrapReason'}->{'syntax'}->{'value
+s'}}) {    print "$_ = ".$x->{'xylanXIPGMAPLastTrapReason'}->{'syntax
+'}->{'values'}->{$_}."\n";
}

Or make it a little easier to read by dereferncing it into a hash:

my %values = %{$x->{xylanXIPGMAPLastTrapReason}->{syntax}->{values}};
foreach(keys %values) {
    print "$_ = $values{$_}\n";
}
