Christian: yeah that is definitely an option.

Peter: I don’t think XStream will do that… Velocity is definitely an option, but still more work than I want it to be.

Try XStream or a template engine (Freemarker, Velocity)

My solution is not using a Person-POJO, but I think a POJO should not be JAXB-annotated to write a microformat. So mapping to an intermediate is IMO a good design decision.

import java.util.*;
import javax.xml.bind.*;
import javax.xml.bind.annotation.*;

public class MicroformatViaJaxb
{
public static void main( String[] args ) throws JAXBException
{
Microformat mf = new Microformat();
mf.elements.add( new Element( “name”, “Christian Ullenboom” ) );
mf.elements.add( new Element( “address”, “1 Main St” ) );
mf.elements.add( new Element( “phone”, “+15555551212″ ) );

JAXBContext context = JAXBContext.newInstance( Microformat.class );
Marshaller m = context.createMarshaller();
m.setProperty( Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE );
m.marshal( mf, System.out );
}
}

@XmlRootElement( name = “div” )
class Microformat
{
@XmlAttribute( name = “class” )
public String key = “person”;

@XmlElement( name = “span” )
public List elements = new ArrayList();
}

class Element
{
@XmlAttribute( name = “class” )
public String key;

@XmlValue
public String value;

public Element()
{
}

public Element( String key, String value )
{
this.key = key;
this.value = value;
}
}

No, I haven’t. But this looks interesting. Because it results in a closer shape to JSON than the typical way people would serialize (your example above). Specifically, if you serialize this way, you could standardize the elements you used for ‘objects’ (div), attributes (span), arrays (ol), etc.

Not AFAIK. That would output something like:

…

The point here is to get out XHTML microcontent as opposed to just straight up XML.

Hey Dan, won’t JAXB, JPOX or the like with annotations on the POJO address this?
