Parsing DOM element to type-specific XMLBean

Hi,

I couldn't get the XmlObject.Factory.parse(Node) to create type-specific XMLBean. The test code is

public class DOM2BeanTest {
    public static void main(String[] args) throws Exception {
        DocumentBuilderFactory dbf = 
DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();

        File file = new File("test/testshib-metadata.xml"); // SAML2.0 Metadata file
        Document doc = 
db.parse(file);
        XmlObject xbean = XmlObject.Factory.parse(doc.getDocumentElement());
        XmlObject xbean2 = XmlObject.Factory.parse(file);
        System.out.println("Type of xbean: "+xbean.getClass());
        System.out.println("Type of xbean2: "+xbean2.getClass());
    }
}

Type of xbean: class org.apache.xmlbeans.impl.values.XmlAnyTypeImpl
Type of xbean2: class x0Metadata.oasisNamesTcSAML2.impl.EntitiesDescriptorDocumentImpl

xbean2 is of correct user-derived type EntitiesDescriptorDocument but the xbean, parsed from a DOM Node, is always of generic type XmlAnyType.

Any idea how to parse the DOM node to XMLBean correctly?

Thanks
