Dbms_xmlgen how to generate encoding attribute

Question

HI, I'm generating XML using the dbms_xml packages. It generates this header
<?xml version="1.0"?> My database has the WE8MSWIN1252 characterset. So I want the header to be:
<?xml version="1.0" encoding="windows-1252"?>My question is how can I generate the xml header automatically, depending on the databases character encoding settings?

You could write (indeed as you mentioned option in 2) your own, for instance, as shown here:
Re: Concatenation, Attributes, and Processing Instruction
and/or use XMLROOT
but that said, you can't use XMLROOT in 9.2 yet.
but based on your requirements it is not easy / a lot of work to do, although I wonder what you are trying to achieve and don't forget that if you pick the database characterset you will probably overrule situations based on:
(http://download.oracle.com/docs/cd/B19306_01/server.102/b14225/ch3globenv.htm#i1006415)
NLS_SESSION_PARAMETERS shows the NLS parameters and their values for the session that is querying the view. It does not show information about the character set.
NLS_INSTANCE_PARAMETERS shows the current NLS instance parameters that have been explicitly set and the values of the NLS instance parameters.
NLS_DATABASE_PARAMETERS shows the values of the NLS parameters for the database. The values are stored in the database.
or in other words if NLS settings are manually changed within a session, instance or database context.
