Sys.XMLType.createxml unable to insert through sqlplus

Question

I am trying to insert xmltype (sys.XMLType.createxml()) data through sqlplus in oracle.
i am getting error as literal string too long.
setting long as 1000000
i am able to read and display the contents.
But still NOT able to INSERT. The data is around 47784 charaters.
any clues or any useful links.
the query that i am using
insert into sometable values("",sys.XMLType.createxml('string of around 48000 chars'));
error that i recieve
ORA-01704: string literal too long

Actually the limit is approx 32K bytes for a SQL*PLUS literal...
If your XML is schema based 9iR2 allows you to upload the XML direct to the database and store in tables you define using FTP or WebDAV.
If the content is not schema based and you can ftp the file to the local file system of the machine running the server you can do something like this using the bfile mechanism.
Note this is a 9iR2 example, that takes care of converting the character set of the file into the character set of the database...
set echo on

drop directory DIR
create directory DIR as '/tmp/xmlDir'
commit
insert into some table values ("",getXML('Filename.xml'));The above example assumes that the file in the directory '/tmp/xmlDir';
