Re: hash ref and yaml

As I suspected, you have one label and refer to it twice:

use YAML;

my $x = { Data => { a => 1, b => 2 } };
$x->{Trans} = [ $x->{Data}, $x->{Data} ];
print Dump( $x );
__END__
---
Data: &1
  a: 1
  b: 2
Trans:
  - *1
  - *1

Perhaps I misunderstood your question. If you want to know whether a YAML document such as you have presented is valid, I suggest looking at the YAML spec to see what it says. I'm not a YAML expert, so I don't have any idea, myself. If you have a file like this and you want to get it loaded, I suggest fixing the file. You could also try loading it with different YAML implementations to see if any will take it.	[reply]
