Jaxb Element Attribute Choice

Question

is there any trick to have two element attributes defined, which excludes each other (similar like choice) ? I know to make it on elements but not on attributes.

@XmlAttribute(name="firstName") 
private String firstName ;
@XmlAttribute(name="lastName") 
private String lastName ;

For example, either element firstName="" or element lastName="" is valid, but not element firstName="" lastName=""

Is this possible ?

Answer 1

There is no attribute choice. You'll need to convert them to full-fledged elements.

Answer 2

If the value mapped with @XmlAttribute is null then it won't be marshaled to XML. You can combine this with some of your own custom logic to get the result you are looking for.
