Read xml into oracle table

Question

Hi,
How can I read an xml.file read in an oracle table (invoice varchar2(20), invoice_line number, ship_date date, country varchar2(100))?
The xml looks like this:
<?xml version="1.0" encoding="utf-8" ?>
- <dataset xmlns="http://developer.cognos.com/schemas/xmldata/1/" xmlns:xs="http://www.w3.org/2001/XMLSchema-instance">
- <!--
<dataset
xmlns="http://developer.cognos.com/schemas/xmldata/1/"
xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"
xs:schemaLocation="http://developer.cognos.com/schemas/xmldata/1/ xmldata.xsd"
>
-->
- <metadata>
<item name="Invoice #" type="xs:string" length="42" />
<item name="Invoice Line" type="xs:string" length="10" />
<item name="Ship Date" type="xs:date" />
<item name="COUNTRY" type="xs:string" length="8" />
</metadata>
- <data>
- <row>
<value>26623</value>
<value>0001</value>
<value>2010-05-03</value>
<value>USA</value>
</row>
- <row>
<value>26624</value>
<value>0001</value>
<value>2010-05-03</value>
<value>USA</value>
</row>
- <row>
<value>26624</value>
<value>0003</value>
<value>2010-05-03</value>
<value>USA</value>
</row>
- <row>
<value>26625</value>
<value>0001</value>
<value>2010-05-03</value>
<value>USA</value>
</row>
</data>
</dataset>
Thnx, Robbert

Hi,
Possible solutions will depend on your db version, which you didn't give.
The following example assumes you're using 10gR2 :
CREATE TABLE invoices (
invoice varchar2(20),
invoice_line number,
ship_date date,
country varchar2(100)
DECLARE
xmldoc xmltype := xmltype(
'<?xml version="1.0" encoding="utf-8" ?>
<dataset xmlns="http://developer.cognos.com/schemas/xmldata/1/" xmlns:xs="http://www.w3.org/2001/XMLSchema-instance">
<metadata>
<item name="Invoice #" type="xs:string" length="42" />
<item name="Invoice Line" type="xs:string" length="10" />
<item name="Ship Date" type="xs:date" />
<item name="COUNTRY" type="xs:string" length="8" />
</metadata>
<data>
<row>
<value>26623</value>
<value>0001</value>
<value>2010-05-03</value>
<value>USA</value>
</row>
<row>
<value>26624</value>
<value>0001</value>
<value>2010-05-03</value>
<value>USA</value>
</row>
<row>
<value>26624</value>
<value>0003</value>
<value>2010-05-03</value>
<value>USA</value>
</row>
<row>
<value>26625</value>
<value>0001</value>
<value>2010-05-03</value>
<value>USA</value>
</row>
</data>
</dataset>'
BEGIN
  INSERT INTO invoices (invoice, invoice_line, ship_date, country)
  SELECT invoice, invoice_line, to_date(ship_date, 'YYYY-MM-DD'), country
  FROM XMLTable(
   XMLNamespaces(default 'http://developer.cognos.com/schemas/xmldata/1/'),
   '/dataset/data/row'
   passing xmldoc
   columns
     invoice      varchar2(20)  path 'value[1]',
     invoice_line number        path 'value[2]',
     ship_date    varchar2(10)  path 'value[3]',
     country      varchar2(100) path 'value[4]'
END;
/If your XML document resides outside the database, you may also access it directly through a DIRECTORY object :
CREATE OR REPLACE DIRECTORY xmldir AS 'C:\oracle\invoices\xml';
INSERT INTO invoices (invoice, invoice_line, ship_date, country)
SELECT invoice, invoice_line, to_date(ship_date, 'YYYY-MM-DD'), country
FROM XMLTable(
XMLNamespaces(default 'http://developer.cognos.com/schemas/xmldata/1/'),
'/dataset/data/row'
passing xmltype( bfilename('XMLDIR', 'invoices.xml'), nls_charset_id('AL32UTF8') )
columns
   invoice      varchar2(20)  path 'value[1]',
   invoice_line number        path 'value[2]',
   ship_date    varchar2(10)  path 'value[3]',
   country      varchar2(100) path 'value[4]'
