I search to make elements ordering.
Why isn't this update also available in nokogiri-happymapper ?
Am I obliged to use nokogiri-happymapper-deiga to get elements ordering ? (or is there any other way, even if more complicated?)
What are the other differences between nokogiri-happymapper and nokogiri-happymapper-deiga ? (is the first abandonned?)

[deiga]

My Pull Request was never accepted, I think nokogiri-happymapper has been abandoned.

Ordering was the only thing I added, here's the changelog

I didn't find any other way, when I was working at the problem.

How do you use the new order attribute ? (I mean, can you give me a syntax exemple, I'm beginner in Ruby)

[quote]Added compatibility with Ruby 1.8.7
Added ordering of elements[/quote]

What has been modified for Ruby 1.8.7 ? That's the version I use but dam5s's happymapper already works on 1.8.7 ?

[deiga]

The gems tests didn't run on 1.8.7 or some such :P You can always check the commits :)

Theres no special syntax there, it just keeps the order of elements. As a Hash in ruby 1.8.7 sorts elements automatically, which broke the order I needed :)

[Danicela]

Do you mean that for Ruby >1.8.7, nokogiri-happymapper already does the correct ordering ?

[deiga]

AFAIK Hashes in ruby 1.9 keep the order of elements according to the order they were added, so yeah, in ruby >= 1.9 the ordering should work intrinsicly

Closing this since according to #55 (comment) this works in all currently supported Ruby versions.
