Serialize XSD Object [message #764951]

I have a object of org.eclipse.xsd.impl.XSDSchemaImpl class of a xsd schema [say A.xsd]. This schema has some <xs:include> tags for including other supporting schemas [say B.xsd and C.xsd]. Now I want to convert this XSDSchemaImpl object into a String such that it include all the element definitions which are defined in the supporting included schema [i.e in B.xsd and C.xsd] will be part of this string. I tried it this way but it gives me only A.xsd in the String.

public Writer writeSchema(XSDSchema schema) throws IOException {
    if (schema == null){
        return;
    }
    URI schemaUri = URI.createFileURI("");
    Resource resource = new XSDResourceFactoryImpl().createResource(schemaUri);
    resource.getContents().add(schema);
    XSDResourceImpl xsdResource = (XSDResourceImpl) resource;
            Writer strWriter = new StringWriter();
    try {
        xsdResource.save(writer, null);
    } finally {
        xsdResource.unload();
    }
            return strWriter ;
}

Manu,

You'll need to actually transform the model into a single schema
instance to get that kind of result. That's not always easy, even just
using DOM, because there could well be conflicting namespace declarations...

Hi Merks

thanks very much for the quick reply. I completely understood the risk of conflicting namespace declarations. My application don't have any such use case. Can you please guide me that what I need to do to transform the model into a single schema
instance to get that kind of result.
Please let me know if you need any other details.

Manu,

Is this something you need to do repeatedly or is there just a single
schema for which you need this? What have you tried so far?

Merks,

I need to do this repeatedly in my application. I also can't merge all the xsd's into one single xsd as it will create lots of duplication and maintenance problem.I have not tried any thing yet as I am not aware of any way by which I can generate one xsd from multiple xsd'd.If you can provide me any pointer that will be great help for me.

XSDPrototypicalSchema has some good examples. The idea would be to
copy/move the contents of the included schema to the including schema.
