paste AuthorDocumentFragment (Oxygen) into TextArea (Java swing)

Question

I want to paste AuthorDocumentFragment (Oxygen) into TextArea (Java swing) of my modal dialog. But the element AuthorDocumentFragment is not supported for textarea. What do I do with this?

My code:

public void doOperation(final AuthorAccess authorAccess, final ArgumentsMap args)
        throws IllegalArgumentException, AuthorOperationException {
   AuthorNode[] nodeList2 = authorAccess.getDocumentController().findNodesByXPath("//*[@id]/child::node()", true, true, true);

    ArrayList<AuthorDocumentFragment> arrayList = new ArrayList<AuthorDocumentFragment>();

    for (AuthorNode i : nodeList2) {
        AuthorDocumentFragment newFragText = null;
        try {
            newFragText = authorAccess.getDocumentController().createDocumentFragment(i, true);
        } catch (BadLocationException e) {
            e.printStackTrace();
        }
        arrayList.add(newFragText);
    }
}

void jList1MouseClicked(java.awt.event.MouseEvent evt) {
    textAreaRefs.setText(???);
}

The AuthorDocumentController API has a method to serialize an AuthorDocumentFragment to XML:
