XML Help -- State of Confusion

Question

If I go to one more White Paper or buy another book on XML I am going to scream..
I got that off my chest. I have what I think is .XML script. I also have an Oracle 10G database. I am attempting to load the data into the database. My steps went something like.
Create a XML DB Repository.... (I got the following error message:
SQL> BEGIN
2 dbms_xmlschema.registerSchema
3 (
4 SCHEMAURL =>'http://xmlns.oracle.com/xdk/message.xsd',
5 SCHEMADOC => bfilename('orbmgr','message.xsd'),
6 CSID => nls_charset_id('AL32UTF8')
7 );
8 END;
9 /
BEGIN
ERROR at line 1:
ORA-22285: non-existent directory or file for FILEOPEN operation
ORA-06512: at "SYS.DBMS_LOB", line 523
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 121
ORA-06512: at line 2
Do I need to create the table of XMLType before I create the repository?

Answer 1

You don't have to buy another new book, but you should read...(i still have to do a lot myself ;-) Nethertheless. A lot of good Mark Drake examples are already on the current forum entry page. Look carefully regarding the dbms_xmlschema.registerschema syntax. Schemaurl shouldn't be the one you are using but something like http://www.mysite.com/blabla (could be a nonexisting one, as long as all references to this namespace are correct). The schemadoc reference is calling a directory called "orbmgr". Does it exist AND is de case-sensitive part correct (look for the CREATE DIRECTORY syntax in the manuals on otn.oracle.com ---> XML DB Developers Guide is an important one, including the SQL reference manual).
If you would lookup the dbms_xmlschema.registerschema syntax you would also see references to input variables like local, etc. see below
dbms_xmlschema.registerSchema
schemaURL (namespace registration of XML schema)
schemaDOC (resource pointer to your XML schema)
local (or global)
genTypes -->generate types
genBeans (not implemented yet / future reference)
genTables --> generate tables
schemadoc --> where does your schema reside?
If you would drag/drop it into the repository via webdav or via ftp then the syntax would be something like
dbms_xmlschema.registerSchema
(schemaURL => 'http://www.mysite.nl/myxsdplace/myxmlschema',
schemaDoc => xdbURIType ('/public/droppedithere/myxmlschema.xsd').getClob(),
local => TRUE,
genTypes => TRUE,
genBeans => false,
genTables => TRUE
CSID => nls_charset_id('AL32UTF8'));
);
