No, that's wrong, and it explains why your data is getting serialized as 
YAML.

Each of your attributes is an array:

  ["1"]

when it should be just a string

  "1"

XmlSimple is giving you an array because you might get multiple elements 
with the same name:

<record>
  <first>foo</first>
  <first>bar</first>
  <first>baz</first>
  ...
</record>

So your code which copies from your XML structure into your ActiveRecord 
model needs changing, e.g. by using .first or [0] to pick the first 
array element.

I have a vague recollection that there's an option you can pass to 
XmlSimple for it *not* to put elements inside arrays; look through the 
docs.
