Yeah, this is the way it is now, and it's a bit much. Especially with a Hash
:)

Actually, I was considering making the type an attribute of the instance
element. So instead of this:

> <MyClass>
>   <SubClass name="sub">
>     <String name="sub_attr">blah</String>
>   </SubClass>
>   <Integer name="an_int">12345</Integer>
> </MyClass>

it'd be:

  <MyClass>
    <sub type="SubClass">
      <sub_attr type="String">blah</sub_attr>
    </sub>
    <an_int type="Integer">12345</an_int>
  </MyClass>

...

That allows the simple types to be eliminated easi-- ... actually, now that
I type this, there's no need for any of the types at all is there? Can't I
query the receiving object for the type of the instance var named in the
element? ... Well, only if it's been initialized, which is not guaranteed
... but if the object is coded to initialize each instance var, then I can
query the type at runtime and there's no need for the type in the XML at
all. Cool!

This is Good. I felt I'd been overlooking something ever since I started
this when I looked at xmarshal and thought, "Odd, Ruby is dynamic, yet this
XML is typed. C# is typed, and its serialized XML is not." My conclusion at
the time was the typing had to be stored somewhere, and C# stores it in the
code, so it doesn't have to in the XML. Well, Ruby has the type, too, if the
instance var is set.

...(testing, rewriting...) ...

hmmm ... this should work, though I've hit upon a weirdness.

It seems that the root node will always have to be the class name, at least
the way the code is structured now. The to_xml call creates the instance var
name node for its instance vars ... because it has this knowledge. The root
to_xml call, doesn't know what the calling code is referring to it as, nor
does it matter.

So ... assuming MyClass initializes its instance vars to the type they
should be when the XML is read in, the XML can be:

  <MyClass>
    <sub>
      <sub_attr>blah</sub_attr>
    </sub>
    <an_int>12345</an_int>
  </MyClass>

Which is cool. But, I'll have to a little jogging around of code so that the
initial to_xml call knows to create a root type node, and all subsequent
calls know not to.

Then, adding an option to store the type as an attribute for anything other
than the root node is a simple switch ... that way anyone without a fully
initialized object (or one who's type should change when the XML is read
in -- weird case, but weird happens) is covered as well.

Thoughts?

Chris
