Hi all,
We have requiremnets to do xml schema conversion between xsd and XMI
formatted. The following code shows how we try to convert a xsd schema to
a XMI formatted file (which conforms to the XSD.ecore model), but the
result file seems not right. I am wondering where the problem is? Maybe
the way I am doing this is wrong? Is there any good way to do such
conversion? What I know is that the XSD package does not use XMI
serialization.
The code:
---
private static void xsd2xmi() throws IOException
{
ResourceSet metaResourceSet = new ResourceSetImpl();
metaResourceSet.getResourceFactoryRegistry().getExtensionToF actoryMap().put(
"xmi", new XMIResourceFactoryImpl());
metaResourceSet.getResourceFactoryRegistry().getExtensionToF actoryMap().put(
"xsd", new XSDResourceFactoryImpl());
URI uriXsd = URI.createFileURI("C:/scheduleXsd.xsd");
Resource r = metaResourceSet.getResource(uriXsd, true);
r.load(null);
XSDSchema schema = null;
if ( r instanceof XSDResourceImpl) {
XSDResourceImpl rXSD = (XSDResourceImpl) r ;
schema = rXSD.getSchema();
}
URI uriXMI = URI.createFileURI("C:/scheduleXmi.xmi");
Resource rXMI = metaResourceSet.createResource(uriXMI);
rXMI.getContents().add(schema);
rXMI.save(null);
}
----
The scheduleXsd.xsd is;
--
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:tns=" http://xml.ms.com/ns/modex-models/atlPrototype-interop/v1_4/ schedule/v2_0"

<xsd:element name="scheduleId" type="xsd:string" minOccurs="0"/>
<xsd:element name="price" type="xsd:double" minOccurs="0"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>

David,
This is related to
https://bugs.eclipse.org/bugs/show_bug.cgi?id=166638. There are no
plans to support this because it's a hard problem to solve (and resource
is lacking). Things like includes (including Chameleon ones) and
imports drive the process of deriving the abstract model from the
concrete syntax of the standard serialization. We'd need to carefully
visit all the features defined in the XSD model to mark things that
shouldn't be serialized as transient and derived.
