Haneef,

There are two ways to parse in an unknown element that has a known type,
which result in slightly different behavior:

METHOD 1:
XmlObject.Factory.parse( MY_EPR, new XmlOptions().setDocumentType(
org.xmlsoap.schemas.ws.x2003.x03.addressing.EndpointReferenceDocument.ty
pe ) );

METHOD 2:
XmlObject.Factory.parse( MY_EPR, new
XmlOptions().setLoadReplaceDocumentElement( new QName(
"http://schemas.xmlsoap.org/ws/2003/03/addressing", "EndpointReference"
)) );

Both will return a
org.xmlsoap.schemas.ws.x2003.x03.addressing.EndpointReferenceDocument,
assuming you have this class in your classpath. The difference is that
when you toString() the returned document XmlBean, method 1 will print
the original name (e.g. wsf:MyEndpointReference), but method 2 will
print the name that you specified when you called parse() (i.e.
wsa:EndpointReference).

The below test program will demonstrate this behavior.

    public static void main( String[] args ) throws Exception
    {
        EndpointReferenceDocument epr = (EndpointReferenceDocument)
XmlObject.Factory.parse( MY_EPR, new XmlOptions().setDocumentType(
EndpointReferenceDocument.type ) );
        System.out.println( epr );
        EndpointReferenceDocument epr2 = (EndpointReferenceDocument)
XmlObject.Factory.parse( MY_EPR, new
XmlOptions().setLoadReplaceDocumentElement( new QName(
"http://schemas.xmlsoap.org/ws/2003/03/addressing", "EndpointReference"
)) );
        System.out.println( epr2 );
    }

}

| Hi,
| 
| Consider the following schema ( this is from ws-addressing)
| 
| 	<compleType name="EndpointRefernceType">
| 		....
| 	</complexType>
| 
| 	<element name="EndpointReference" type="EndpointReferenceType"
| />
| 
| A) I do have compiled xmlbeans2.0 stubs for the above schema. 
| B) Assume user creates the following  xml fragment
| 
| 	<?xml  version="1.0" ?>
| 	<MyEndpointReference xsi:type="EndpointRefernceType">
| 		....
| 	</MyEndpointReference>
| 
| 	
| Is it possible for me to parse this fragment? I don't have 
| stubs for "MyEndpointReference". I do have stubs for its 
| type. Using it I'm able to parse , but I'm not able to get 
| any value, since all the values are null.
| 
| Questions:
| 	1) Any idea how can I parse and get the contents?  I 
| don't want to use XmlCurosr, as I will loose the type information.
| 	2) What is the use of  EndPointReferneceType.Factory.parse(),
| Only if parsed using the corresponding document, class I''m 
| getting proper values.
| 	3) Is there an alternate way to handle type/instance 
| with xmlbeans. I don't want to create stubs ( I can't create 
| stubs) for instance, but can create stubs for type.
|

| Haneef
