ISSUES IN XML FILE HEADER

Question

Hi Gurus,
I am facing issue with the first two lines in incoming XML file. I am unable to read this using my program.
<?xml version="1.0"?>
<GL_INTERFACE_TBL xmlns="http://xmlns.oracle.com">I am pasting first few lines of my sample code.
DECLARE
    lv_supp_file     XMLTYPE;
  BEGIN
    lv_supp_file  := xmltype( bfilename('XMLDIR','GL_XML_0512.xml'), nls_charset_id('AL32UTF8'));If first two lines are like this then I can read the file easily.
<?xml version="1.0" encoding="UTF-8"?>
<GL_INTERFACE_TBL>
OR
<?xml version="1.0" encoding="UTF-8"?>
<GL_INTERFACE_TBL xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">Please confirm is there any way. Our third applications does not have UTF-8 character set.
Regards,
Nagendra

You still don't give the error message.
Don't you think it's important for diagnosing the problem?
When I try to read that incoming XML file I am encountering errors. Is it possible to make programs compatible in reading such kind of files.Sure.
You have to determine what's the real encoding of the XML file (ask the third party team if necessary).
Normally, when the encoding specification is missing in the prolog (like what you're receiving), then the file is considered UTF-8, but obviously it's not the case here.
When you know the real encoding, you must then specify the corresponding character set in the XMLType constructor.
For example, if the encoding is ISO-8859-1, then you must use this instead :
lv_supp_file  := xmltype( bfilename('XMLDIR','GL_XML_0512.xml'), nls_charset_id('WE8ISO8859P1'));
