Hello michaels , thank you for the solution, still i am having some problems
Here is what i have done :
1.
SQL> CREATE DIRECTORY my_table_dir AS 'E:\table_files'
2 ;
Directory created.
2.
SQL> select * from myemp;
ENAME
SMITH
ALLEN
3.
This is the content of the existing xml file saved in the directory E:\table_files as emp.xml
<EMPLOYEES>
<EMP>JIM</EMP>
<EMP>RICK</EMP>
</EMPLOYEES>
4.
Now i executed this code :
declare
emp_xml xmltype;
begin
select sys_xmlagg (column_value, sys.xmlformat ('EMPLOYEES')) emp_xml
into emp_xml
from table (xmlsequence (cursor (select *
from myemp
where ename in ('SMITH', 'ALLEN')),
sys.xmlformat ('EMP')
dbms_xslprocessor.clob2file (emp_xml.getclobval (), 'E:\table_files', 'emp.xml');
end;
And the Error i got is :
declare
ERROR at line 1:
ORA-29280: invalid directory path
