I get the xml content with the following code.
code:

EPackage poPackage = EcoreFactory.eINSTANCE.createEPackage();
EFactory eFactory=poPackage.getEFactoryInstance();

EClass purchaseOrderClass = EcoreFactory.eINSTANCE.createEClass();
purchaseOrderClass.setName("PurchaseOrder");
poPackage.getEClassifiers().add(purchaseOrderClass);

EClass itemClass = EcoreFactory.eINSTANCE.createEClass();
itemClass.setName("Item");
poPackage.getEClassifiers().add(itemClass);

EAttribute nameAttribute =
EcoreFactory.eINSTANCE.createEAttribute();
nameAttribute.setName("name");
nameAttribute.setEType(EcorePackage.eINSTANCE.getEString());
itemClass.getEStructuralFeatures().add(nameAttribute);

EAttribute shipToAttribute =
EcoreFactory.eINSTANCE.createEAttribute();
shipToAttribute.setName("shipTo");
shipToAttribute.setEType(EcorePackage.eINSTANCE.getEString());
purchaseOrderClass.getEStructuralFeatures().add(shipToAttribute);

EReference eReference = EcoreFactory.eINSTANCE.createEReference();
eReference.setName("items");
eReference.setEType(itemClass);
eReference.setUpperBound(ETypedElement.UNBOUNDED_MULTIPLICITY);
eReference.setContainment(true);
purchaseOrderClass.getEStructuralFeatures().add(eReference);


EObject order = eFactory.create((EClass)(poPackage.getEClassifier("PurchaseOrder")));
order.eSet(order.eClass().getEStructuralFeature("shipTo"), "there");
EObject item1 = eFactory.create((EClass)(poPackage.getEClassifier("Item")));
item1.eSet(item1.eClass().getEStructuralFeature("name"), "item1");
((List)order.eGet(eReference)).add(item1);
EObject item2 = eFactory.create((EClass)(poPackage.getEClassifier("Item")));
item2.eSet(item2.eClass().getEStructuralFeature("name"), "item2");
((List)order.eGet(eReference)).add(item2);


final ExtendedMetaData data=new BasicExtendedMetaData(ExtendedMetaData.ANNOTATION_URI,EPackage.Registry.INSTANCE,new HashMap());
data.setFeatureKind(eReference, ExtendedMetaData.ELEMENT_FEATURE);
//data.setFeatureKind(nameAttribute, ExtendedMetaData.ELEMENT_FEATURE);
data.setGroup(eReference, eReference);
data.setName(purchaseOrderClass, "poo");

Map options=new HashMap();
options.put(XMIResource.OPTION_EXTENDED_META_DATA, data);

ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("xml",new XMIResourceFactoryImpl());
URI fileURI = URI.createFileURI(new File("d:/temp/mypo.xml").getAbsolutePath());
Resource poResource = resourceSet.createResource(fileURI);
poResource.getContents().add(order);
try {
poResource.save(options);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

the result Xml is

<?xml version="1.0" encoding="ASCII"?>
<poo xmi:version="2.0" xmlns:xmi="" shipTo="there">
<items name="item1"/>
<items name="item2"/>
</poo>


but i need the xml like


<?xml version="1.0" encoding="ASCII"?>
<poo xmi:version="2.0" xmlns:xmi="" shipTo="there">
<items>
<item name="item1"/>
<item name="item2"/>
</items>
</poo>


Thanks!!!!!!!!!!!!!!!

You probably also want to avoid the term "poo" after you've looked it up in a dictionary :P

A valid XMI serialization must use the xmi prefix on the root
element.   Maybe you want to try XM<b>L</b>ResourceFactoryImpl.<br>
