I do it This Way:
/*-- Reading XML File have to create Directory 'TEST_DIR' --*/

declare xDoc xmltype := xmltype(BFILENAME('TEST_DIR','TestData.xml' ),('AL32UTF8'));
rc_xml sys_refcursor;
begin
open rc_xml for select xt.* from xmltable('//Root/Data'
passing xDoc
column
"ColumnName" datatype Path 'ElementName',
"ColumnName" datatype Path 'ElementName') XT;
end;

Hi thanks for the reply, but actually we have more than 10 folders/drives from different servers so how to loop that and fetch those xml files data into a DB Table or tables.

For security reason, Oracle does not (and should not) read files on other servers.

Probably you should pass parameter from front-end application and do all looping there.

Actually concept is not like that, we will have a individual server only,
which has a Drive(eg: D:\folder1\sh1.xml) containing folders which hold
xml files so just the concept is to find each folders which containing the xml files.

The need is that we have not only one files but different files from different folders,
but in a specific drive, a folder has more than one files.

example:

d:\folder1\sh1.xml
d:\folder1\sh2.xml
d:\folder2\w1.xml
d:\folder2.w1.xml

The following provides references to two different methods of obtaining file names from an operating system directory. You can then loop through those, selecting only the xml files, then do whatever you want with those files.

ORA-22288: file or LOB operation %s failed\n%s
 *Cause: The operation attempted on the file or LOB failed.
 *Action: See the next error message in the error stack for more detailed
          information.  Also, verify that the file or LOB exists and that
          the necessary privileges are set for the specified operation. If
          the error still persists, report the error to the DBA.
