/select * from emp;
this file works fine
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<ipdrIPDR>
<recordId>923622</recordId>
</ipdrIPDR>
but this is not . .. note my special charter in the tokens... i did change in the program too but does not work ...
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<ipdr:IPDR>
<recordId>923622</recordId>
</ipdr:IPDR>
I get error
errrrrrrrr--->ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00234: namespace prefix "ipdr" is not declared
Error at line 2

Hi,
Yes, I have tried the same method. will be ok.
But I have got another some records on the same column as follows.
I have tried with another one xmltable with outer join(+), still not getting the actual data (null record from the original(main) table) and extra records from the new xmltable.
Is it possible to make one or union with xmltable also can we check the node either /Item or /section exists something like that
<?xml version="1.0" encoding="WINDOWS-1252"?>
<section>
  <sectionmetadata>
    <object_id>317832</object_id>
    <asitype>Section</asitype>
    <instructornotes/>
  </sectionmetadata>
  <selection_ordering>
    <selection seltype="All">
