How to add processing instruction to my XML view

Question

Hi,
How do I add the processing instruction like <?xml version="1.0" encoding="iso-8859-1"?>.
in my XML view.

Answer 1

The only way to do at the moment is as follows... And it's not very pretty. The SQL/XML standard is still finalizing the correct way of doing this...
set echo on
connect &1/&2@&3
create or replace view EMPLOYEES_WORKBOOK_XML of xmltype
xmlschema "excel.xsd" element "Workbook"
