xds4r documentation?
Patrick Chanezon
I'd like to generate class files from an xsd schema and it seems to me that xsd4r looks like a good candidate.
Is it true?
Is it part of soap4r?
Where can I find more docs about that?
Thanks in advance.

xsd4r is a module name which is located in lib/xsd and
lib/wsdl/xmlSchema. It's for XML Schema handling so it might help you.
But it's for WSDL for now (different from JAXB) so all you can do is
generating classdef file from XML Schema definition with bin/xsd2ruby.rb
To say the truth,
xsd2ruby.rb --xsd
is just the same as
wsdl2ruby.rb --classdef
There's no document, as ever. Sorry about that.

The Mapping module seems to be at the heart of that, but I don't understand how it works.
def self.obj2xml(obj, elename = nil, io = nil)
instead of
def obj2xml(obj, elename = nil, io = nil)
Are these class methods?
include Mapping in the generated classes does not help, and when I use the methods as calss methods it does not serialize recursively.
Any hints?
Do I need to build a MappingRegistry?

1. xsd2ruby.rb is just for generating classdef file in Ruby.
2. XSD::Mapping.obj2xml and XSD::Mapping.xml2obj are for XML <-> Ruby
object mapping using class definition, such as a one generated by
xsd2ruby.rb
XML <-> Ruby object mapping based on MappingRegistry is only works for
WSDL. (I should not write it clearly in the previous mail. Sorry.)
Can you prepare WSDL file which only contains your XML Schema definition
in <schema/> tag? Then you can get custom MappingRegistry with
% wsdl2ruby.rb --classdef --mapping_registry
Then, replacing MappingRegistry in
lib/xsd/mapping.rb(XSD::Mapping::MappingRegistry) may work. Do you have
a sample XSD file? I'll try it.

Thanks that worked.
Then, replacing MappingRegistry in
lib/xsd/mapping.rb(XSD::Mapping::MappingRegistry)
Oh you mean replacing the file itself so that my classes get the module DefaultMappingRegistry instead of the one from XSD?
How do I use these mappings aftert hat?
Something like?
require 'defaultMappingRegistry.rb'
price = Money.new('10')
price.xmlattr_currency = 'USD'
items = Array.new
items[0] = Item.new("Cool Google Checkout T-shirt", "Google T-Shirt", nil, 2, nil, price)
cart = ShoppingCart.new(CartExpiration.new(Date.new()), items, nil)
gccart = CheckoutShoppingCart.new(nil, cart)
#XSD::Mapping.obj2xml(gccart, nil, STDOUT)
#map = ::XSD::Mapping::MappingRegistry.new
#map = ::SOAP::Mapping:: Registry.new
gccart.obj2xml(gccart, nil, STDOUT)

Your reply has helped me out too. One more question. I want the
specified classname to become the generated file name. Looking at the
code I don't think it does that. Correct?
I would like to be able to extend the bin/xsd2ruby.rb to codegen all
xsd files in a directory, but if defaults to naming the generated file
default.rb this won't work.
Any ideas?
Thanks.

I've just added a feature to xsd2ruby.rb, the feature is for generating
mapping registry from XML Schema. Now it works like the following;

I don't think that this empty example demonstrates this feature enough.
And it must be too late for you... Writing this for the person who
will be interested in Ruby XML mapping based on XML Schema.

Yes, it was two minutes ago. Now xsd2ruby.rb accepts the option:
- --classdef [basename]

In the meantime some of our users have created manual parsers: http://google4r.rubyforge.org/
I really appreciate that you improved xsd2ruby to be able to support the checkout schema. This improves the ruby platform for everyone, and we may end up using it in later versions of google4r.
It may be useful for the gdata client lib as well, (none in ruby yet) whenever they publish a schema http://groups.google.com/group/google-help-dataapi/browse_thread/thread/90473c430792dd95 :-)
I'll give xsd2ruby.rb another shot this summer.

I'd like to use xsd2ruby like XMLToSQL in java. (It is used to insert,
update, or delete rows in a database table using an XML document).
At least to generate a SQL-databas. Is it possible?
Thanks in advance.

I don't know XMLToSQL well but from your explanation above, it's hardly
doable I think. xsd2ruby.rb is for generating stub files from XML
Schema for mapping Ruby object and XML.
