REF and xmltype

Question

Hi,
I cannot find a sample to user REF and xmltype in oracle docs.
I want to create a resource (in a folder in xmldb resource) using dbms_xdb.createresource with a REF xmltype.
Could you help me,
Regards,
Olivier

From the XML DB standard demo
declare
  cursor getDepartments is
    select ref(d) XMLREF,
           XMLCast( XMLQUery ( '$d/Department/Name' passing object_value as "d" returning content) as VARCHAR2(32) ) NAME
      from DEPARTMENT_XML d;
  res boolean;
  targetFolder varchar2(1024) :=  '/home/SCOTT/Departments';
begin
  if dbms_xdb.existsResource(targetFolder) then
     dbms_xdb.deleteResource(targetFolder,dbms_xdb.DELETE_RECURSIVE);
  end if;
  res := dbms_xdb.createFolder(targetFolder);
  for dept in getDepartments loop
    res := DBMS_XDB.createResource(targetFolder || '/' || dept.NAME || '.xml', dept.XMLREF);
  end loop;
end;
select path
  from path_view
where under_path(RES,'/home/SCOTT/Departments') = 1
