I am new to XML. After spending a lots time in reading, still can't figure out how to extract sub nodes from multi nodes in this file. Really appreciate your help.

This is awesome!! You have cured my three-days headache. Now I only need to create a function to concatenate values in the column CODE group by CUSTOMERPONUM. Thank you so much!!

Here is an alternate 11g syntax that has a littler more flexibility, as you can specify column types and sizes.

You can use any of various string aggregation techniques, such as listagg in the demonstrations below.

The code works when I am using the xmltype(string). However,I inserted the xml document into the table temp (xml_doc xmltype), and got an error when running this:
WITH data AS (SELECT xml_doc FROM temp),
     columns
         AS (SELECT EXTRACTVALUE (x.COLUMN_VALUE, 'Orders/LeasingCoNum')

                        customerponum,
                    EXTRACTVALUE (z.COLUMN_VALUE, 'Code') code
               FROM data t,
                    TABLE (XMLSEQUENCE (EXTRACT (t.xml_doc, 'Orders'))) x,
                    TABLE (

SELECT leasingconum,
       customerponum,
       listagg (code, ',') WITHIN GROUP (ORDER BY code) codes
  FROM columns
GROUP BY leasingconum, customerponum;

ORA-00600/ORA-07445/ORA-03113 = Oracle bug => search on Metalink and/or call Oracle support
Have a look at alert.log and trace files.
