Hi all,
I'm facing a problem with XML file loading. I have an Ecore model generated from a XSD schema, and I want to load a preexisting XML file, conform to this schema, with EMF. Unfortunately, during the loading process, some features do not seem to be recognized. I include here the code I used to load the XML file. Do I forgot some loading options ?
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("xml", new XMLResourceFactoryImpl());
EPackage.Registry.INSTANCE.put("http://example.com/mp", MyPackage.eINSTANCE);
ResourceSet resourceSet = new ResourceSetImpl();
Map<String, Object> options = new HashMap<String, Object>();
options.put(XMLResource.OPTION_EXTENDED_META_DATA, Boolean.TRUE);
Resource resource = resourceSet.createResource(URI.createURI("model/file.xml"));
resource.load(options);
The generated Ecore model.
@ExtendedMetaData(name="models", kind="elementOnly")
class ModelsType {
@ExtendedMetaData(kind="element", name="dtdVersion", namespace="##targetNamespace")
!resolve val DtdVersionType dtdVersion;
@ExtendedMetaData(kind="element", name="momMetaData", namespace="##targetNamespace")
!resolve val MomMetaDataType momMetaData;
@ExtendedMetaData(kind="element", name="mim", namespace="##targetNamespace")
!resolve val MimType[*] mim;
@ExtendedMetaData(kind="element", name="interMim", namespace="##targetNamespace")
derived !resolve val InterMimType[*] interMim;
}
A excerpt of the XML file, that causes me some troubles.
<models xmlns="http://example.com/mp">
<mim name="MODEL_M" version="1" release="32"> // that is line 83
<applicationTag>Includes the ... </applicationTag>
<struct name="ValueOfUnex">
<description>The attributes in ....</description>
<structMember name="vpi">
<description>The ATM header vpi.</description>
<long>
<defaultValue>0</defaultValue>
</long>
...
And the raised exception log.
Exception in thread "main" org.eclipse.emf.ecore.resource.Resource$IOWrappedException: Feature 'mim' not found. (file:///C:/../file.xml, 83, 58)

Guillaume,
Try invoking Generate Test Code and have a look at MyExample.java in the
*.tests project. You'll notice it registers the generated
MyResourceFactoryImpl which sets the right options you'll need.

It's generally best to use an absolute URI with an absolute path.
Again, see how the generated example does this.
