| Serializing EMF Model with XML - Top Element [message #429722] |

Hi!
Today I tried to serialize my EMF Model to XML. I found out that the
XMLSaveImpl class (which does the work of serialization) writes only the
first object from the XMLResource' contents.
protected Object writeTopObjects(List<? extends EObject> contents)
{
return writeTopObject(contents.get(0));
}
If I add several objects to the XMLResource' contents, only the first
object is serialized.
Is there a best practice how to add a top level object, or do I have to
create a root object in my model?
Regards,
Christoph

You can use an XMIResource to save multiple roots; it will inject a
"fake" XMI root element to hold the contents. In general of course, XML
only allows one root element, so unless you're happy with an XMI
serialization, yes you'll have to define a root object to hold the
multiple children...
