Getting YAML elements out in the file order

[deane.barker]

I have a YAML file which I get into Ruby using the "load" method of the
YAML class.

I would like Ruby to respect the order of elements in the YAML file, so
I could get them out of the object in the same order they appear in the
file.

Is this possible? Ruby puts the elements into a Hash, which famously
doesn't promise any ordering when the elements come out, so I'm not
optimistic.

So, is it possible to get elements out of a YAML object in Ruby in the
same order that they appear in the file, or should I move on to another
way of doing it?

why not using a separate array which contains the same elements as the
hash but in the order of your choice? YAML will store the data only once
and maintains a reference list for the array, so your file will not be
much bigger in size.
Just try it and see if it meets your taste..
