Importing XML into oracle 11g database

Question

I am having some difficulty parsing an XML file into oracle 11g database.
Currently using Oracle 11g Express Edition (XE)
Here is how my XML file looks like:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- <AccountMap xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
- <Accounts>
- <AccountMapping>
<AccountID>0000000000000-000</AccountID>
<AccountName>XLS</AccountName>
<AccountType>Excel</AccountType>
<AccountOwner>System</AccountOwner>
</AccountMapping>
- <AccountMapping>
<AccountID>0000000000000-001</AccountID>
<AccountName>XLSS</AccountName>
<AccountType>Excel2</AccountType>
<AccountOwner>System2</AccountOwner>
</AccountMapping>
- <AccountMapping>
and so on the file continues.. I have the xml file saved on my local hard disk
I have created a package in SQL Developer
create or replace
PACKAGE XML_FILEHANDLER AS
type TRecord is record (
Account_ID varchar2(100)
, AccountName varchar2(100)
, AccountType varchar2(30)
, AccountOwner varchar2(100)
type TRecordTable is table of TRecord;
function getRows (p_directory in varchar2, p_filename in varchar2) return TRecordTable pipelined;
END XML_FILEHANDLER;
-- BODY
create or replace
PACKAGE BODY XML_FILEHANDLER AS
function getRows (p_directory in varchar2, p_filename in varchar2) return TRecordTable pipelined AS
nb_rec NUMBER := 1;
tmp_xml CLOB;
tmp_file CLOB;
rec TRecord;
BEGIN
dbms_lob.createtemporary(tmp_file, true);
tmp_file := dbms_xslprocessor.read2clob(p_directory, p_filename);
rec.Account_ID := regexp_replace(tmp_file, '.*<Account_ID>(.*)</Account_ID>.*', '\1', 1, 1, 'n');
rec.AccountName := regexp_replace(tmp_file, '.*<AccountName>(.*)</AccountName>.*', '\1', 1, 1, 'n');
rec.AccountType := regexp_replace(tmp_file, '.*<AccountType >(.*)</AccountType >.*', '\1', 1, 1, 'n');
rec.AccountOwner := regexp_replace(tmp_file, '.*<AccountOwner>(.*)</AccountOwner>.*', '\1', 1, 1, 'n');
loop
-- this regexp finds occurrence(s) of this pattern : "<?xml ... ?><root_tag> ... </root_tag>"
tmp_xml := regexp_substr(tmp_file, '<\?xml[^?]+\?>\s+<([^>]+)>.*?</\1>', 1, nb_rec, 'n');
exit when length(tmp_xml) = 0;
--dbms_output.put_line(tmp_rec);
nb_rec := nb_rec + 1;
SELECT Account_ID, AccountName, AccountType, AccountOwner
into rec.Account_ID, rec.AccountName, rec.AccountType, rec.AccountOwner
from xmltable(
'Accounts/AccountMapping' passing xmltype(tmp_xml) columns
Account_ID varchar2(100) path 'Account_ID'
, AccountName varchar2(100) path 'AccountName'
, AccountType varchar2(30) path 'AccountType'
, AccountOwner varchar2(100) path 'AccountOwner'
pipe row ( rec );
end loop;
dbms_lob.freetemporary(tmp_file);
END getRows;
END XML_FILEHANDLER;
-- I am calling my function using the following sql query
select * from table(XML_FileHandler.getRows('XML', 'test.xml'));
Here is the error I am receiving
ORA-29283: invalid file operation
ORA-06512: at "SYS.UTL_FILE", line 536
ORA-29283: invalid file operation
ORA-06512: at "XDB.DBMS_XSLPROCESSOR", line 265
ORA-06512: at "user.XML_FILEHANDLER", line 13
29283. 00000 - "invalid file operation"
*Cause:    An attempt was made to read from a file or directory that does
not exist, or file or directory access was denied by the
operating system.
*Action:   Verify file and directory access privileges on the file system,
and if reading, verify that the file exists.
I have done the following
- Provided appropriate access to user (read, write) including directory access rights
- ensured that directory exists
- ensured that file exists
I have searched all over google and metalink but am unable to get this to run.. please help!
