[castor-user] Problems getting attribute values from elements with no value

[daniel . martin]

Hello,

I am generating Castor objects from an XML schema that I cannot change. 
Most of the elements in the schema are defined such that the element 
itself has no value, with the actual value being contained in an 
attribute:

        <xsd:complexType name="VersionType">
                <xsd:annotation>
                        <xsd:documentation>
                                <Uid>ET0002</Uid>
                                <Definition>A code...</Definition>
                        </xsd:documentation>
                </xsd:annotation>
                <xsd:attribute name="v" use="required">
                        <xsd:simpleType>
                                <xsd:restriction base="xsd:integer">
                                        <xsd:minInclusive value="1"/>
                                        <xsd:maxInclusive value="999"/>
                                </xsd:restriction>
                        </xsd:simpleType>
                </xsd:attribute>
        </xsd:complexType>

The schema then has an element as such:

                                <xsd:element name="MessageVersion" 
type="ecc:VersionType">
                                        <xsd:annotation>
                                                <xsd:documentation/>
                                        </xsd:annotation>
                                </xsd:element>

The xml data file being unmarshalled has the element:

  <MessageVersion v="1"/>

When I unmarshall this file and call getMessageVersion() I am getting null 
in return.  This makes it impossible to read the attribute value in the 
MessageVersion object.

Is there a way to get Castor to create a MessageVersion object on the 
unmarshall so I can retrieve the attribute value?

Thanks,
Dan  :)
