Here is an example of how you could support this use case.
Mapping Document (bindings.xml)
You could use the xml-elements mapping for this use case. On each of the nested xml-element mappings you would specify a different xml-path.
<?xml version="1.0"?>
<xml-bindings
xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm"
package-name="forum17977009">
<java-types>
<java-type name="Content">
<xml-root-element/>
<java-attributes>
<xml-elements java-attribute="elements">
<xml-element xml-path="a/b"/>
<xml-element xml-path="c/d"/>
</xml-elements>
</java-attributes>
</java-type>
</java-types>
</xml-bindings>
Java Model (Content)
Below is the Java model we will use for this example.
package forum17977009;
import java.util.List;
public class Content {
private List<ElementType> elements;
public List<ElementType> getElements() {
return elements;
}
public void setElements(List<ElementType> elements) {
this.elements = elements;
}
}
jaxb.properties
To specify MOXy as your JAXB provider you include a file called jaxb.properties in the same package as your domain model with the following entry (see: http://blog.bdoughan.com/2011/05/specifying-eclipselink-moxy-as-your.html).
javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory
Input (input.xml)
Below is a sample input document.
<?xml version="1.0" encoding="UTF-8"?>
<content>
<a>
<b/>
<b/>
</a>
<c>
<d/>
<d/>
</c>
</content>
Demo
Below is some demo code you can run to prove that everything works:
package forum17977009;
import java.io.File;
import java.util.*;
import javax.xml.bind.*;
import org.eclipse.persistence.jaxb.JAXBContextProperties;
public class Demo {
public static void main(String[] args) throws Exception {
Map<String, Object> properties = new HashMap<String, Object>(1);
properties.put(JAXBContextProperties.OXM_METADATA_SOURCE, "forum17977009/bindings.xml");
JAXBContext jc = JAXBContext.newInstance(new Class[] {Content.class}, properties);
Unmarshaller unmarshaller = jc.createUnmarshaller();
File xml = new File("src/forum17977009/input.xml");
Content content = (Content) unmarshaller.unmarshal(xml);
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(content, System.out);
}
}
Output
Since all of the items are of the same type, they will output based on the xml-path of the first xml-element in the xml-elements mapping:
<?xml version="1.0" encoding="UTF-8"?>
<content>
<a>
<b/>
<b/>
<b/>
<b/>
</a>
</content>
