Documentation of ActiveRecord 422 errors xml

I'm creating a active resource connection to a legacy program. I implemnted it using the 422 validation response in the documentation. There is a typo in the documentation in ActiveResource::Base under validation:

<errors type="array"><error>First cannot be empty</error></errors>

The attribute type="array" doesn't belong there. Luckily there is always code to fall back on ;) The Errors.from_xml just eats the errors when implemented as the documentation point out.

# Grabs errors from the XML response.
def from_xml(xml)
  array = Array.wrap(Hash.from_xml(xml)['errors']['error']) rescue []
  from_array array
end
