Hello everybody!

I would like to be able to transform an emf model in xml.

I have created a metamodel (ecore file and a genmodel file).
In the genmodel file I choose the option to generate the xml model.
So at the generation, a xsd file and a xsd2ecore file.
But I don't know how to use it to transfom ons model in xml.
I don't really find documentation for the xsd2ecore file.

Someone know how can I do that ?

Sorry for my baf english.

Thanks;

Jérémie

Thanks ed for your links.

But in fact, I would like the oposite.
I wil try explain better.
I have my metamodel ecore. (for ecemple Entity.ecore)
with that I can generate model files (for exemple test1.entity)

The generation (with the genmodele created 2 files :
* Entity.xsd
* Entity.xsd2ecore

now I would like to transform my file test1.entity to an xml file (test1.xml) wich can be validate with the xsd file entity.xsd.

I hope this new explication is better,

Regard;

jeremie

If you Export your Ecore model (using the GenModel) to an XML Schema
(or XMI Schema, depending on what type of serialization you use for
*.entity) then the result should be a schema to which *.entity already
conforms.

I have the same problem.

I am able to convert my ecore meta model to a standard xml schema. But my model instances that are conform to the ecore meta model are of course not conform to the xml schema. So i have to convert them anyhow.

Any hints?

Thanks a lot
Till

How are your serialized instances different from the one you'd expect
based on the exported schema?

My main issue are the references that are using the EMF style instead of XPath

Nothing is going to get it to use XPath. We can't even interpret Xpath
when we read the instance...

Yea, that was what i thought. It's really a problem to read instances with other languages like C++ since no XML parser understands the references correctly.
