Turning EMF into XML/XMI without using a resource [message #523935]

I have EMF objects in a resource set that stores the resources in a database. I want to be able to
turn those EMF objects into XML to pass them to other applications in XML/XMI format. However,
since they are not stored as XML, I need to convert them. I can copy them into a XMIResourceSet and
use that, but that means I have two resource sets holding identical data. Is there anyway to
avoid that and turn EMF objects directly into XML? Thanks.

You could copy it, put it in a resource that's not in the resource set,
and then let it all be garbage collected when it's done.

I do it like this:
First copy the root element of the subtree you want to export:

newResource.getContents().add(copyOfRoot);
ByteArrayOutputStream out = new ByteArrayOutputStream();
try {
newResource.save(out, null);
} catch (IOException e) {
throw new WhatEverException("Something wrong", e);
}
