One solution is to write a custom FieldHandler that can check to see if
your field is "empty". If so simply return null from the getValue()
method in the FieldHandler.
For more on writing FieldHandler's please see:

Hope that helps,

Hi,
I think you're correct in your assumption that it's because you have
instance of the object itself. It is this that represents the parent tag
in Castor terms. So you have to null this reference to have it not
output the parent tag. In order to implement this I guess Castor would
have to know if an object is "empty" in XML terms. Something I know it
doesn't do already, sorry.
Cheers,
Andy.

Subject: [castor-user] how to avoid empty elements ?
Hi,
I'm using Caster to marshal a List of javabeans to xml. Sometimes one
of these beans is not null, but all of it's fields are empty. In that
case, Castor just outputs the xml with all elements empty. Is there a
way to tell Caster not to write the xml when this is the case ?
Thanks
Henk
PS I tried to look this up in the forums or the wiki, but both are
unreacheable for the moment.
