Generate XML document

Question

Hi,
My problem is about generating XML document. I'd like to be able to generate automaticaly (like what we can get at this kind of URL http://xdbserver:8080/oradb/USER/table_name) XML documents for any relational tables, I want the document being schema based and I want to store them in XDB in the repository.
I do not really matter at the time the way the xml is generated (I just do not want that it takes hours). Is there a way to do that with PL/SQL package or with a java classes?
Thanks in advance.

1)I'm using this PL/SQL proc to create XML :
(table_name in VARCHAR2)as --generation d'un fichier xml basé sur un schéma pour la table dont le nom est passé en paramètre
qryCtx DBMS_XMLGEN.ctxHandle;
result XMLType;
begin
qryCtx := dbms_xmlgen.newContext('SELECT * from VLAD.' || table_name);
-- set the row header to be EMPLOYEE
DBMS_XMLGEN.setRowTag(qryCtx, table_name);
-- now get the result
result := DBMS_XMLGEN.getXMLType(qryCtx,2); --2 for XMLSchema (1 for a DTD)
--insertion de result dans la table tempo
insert into tempo values(result);
--close context
DBMS_XMLGEN.closeContext(qryCtx);
exception
when others then
dbms_output.put_line(TO_CHAR(sqlerrm));
end;
I saw in the doc that DBMS_XMLGEN.getXMLType(qryCtx,2) with the "2" was for schema but what does it do exactly, does it generate a schema against the table_name?
2)I'd like to put the result which is XMLType in a XML file in the server, is there a way to do it with UTL FILE?
