Generate XML output using DBMS_XMLGEN.getxmltype and not from rdf

Question

Hi,
I have a requirement to display output from a particular table in XL format. Out of all the known possible options, I am planning to use the XML publisher to generate XL output.
For the data source, instead of using the conventional way of creating XML data using rdf,I am planning to use DBMS_XMLGEN.getxmltype pl/sql procedure to generate the XML output. And from the output, call the template to generate the required Excel output.
Now, I am using the following code to generate XML output but am not sure how to proceed from here. I need to first print the XML data in the FND Output file after which I was planning to call the 'XML Report Publisher' (XDOREPPB) program and use the current request id to get the excel output but I am not able to find the way to print the XML data in the output file as:
fnd_file.put_line (fnd_file.output, l_xml_type); - is throwing an error as l_xml_type is an XML data output.
PROCEDURE xml_main (
errbuf OUT VARCHAR2
,retcode OUT VARCHAR2
,p_project_from IN VARCHAR2
,p_project_to IN VARCHAR2
AS
l_xml_type XMLTYPE;
BEGIN
SELECT DBMS_XMLGEN.getxmltype
('SELECT fnd_global.conc_request_id
,TO_CHAR (segment1)
,to_char(start_date,''MM/DD/RRRR'')
,to_char(xxmcc_project_details_pkg.current_profit_projection
(project_id),''999,999,990.90'')
,to_char(xxmcc_project_details_pkg.cost_to_date (project_id),''999,999,990.90'')
,''1''
FROM pa_projects_all
WHERE segment1 BETWEEN NVL (p_project_from, segment1)
AND NVL (p_project_to, segment1)')
INTO l_xml_type
FROM DUAL;
     fnd_file.put_line (fnd_file.output, l_xml_type);
END xml_main;
Can anyone point me as to how to publish XML output using a PL/SQL procedure (DBMS_XMLGEN.getxmltype)
Thanks.

Pl see if the example included in this presentation helps http://www.oracle.com/technology/products/applications/Events/OOW-2006/EBS/S281401_Sridhar_Bogelli.pdf
Also, you do not need to explicitly call XDOREPPB in later versions of XML Publisher. If you set up everything correctly (as described in the presentation above and the link below) the Output Post Processor is called automatically after the XML file is generated successfully.
