Using XML in Oracle

Question

Good Morning!
I wanted to insert some xml Data into my Orcale XML DB:
First of all I registered 2 Schemas required for the XML, like this:
Begin
DBMS_XMLSCHEMA.registerSchema(
schemaURL => 'Mailpiece_Processing/oif_dtypes',
schemaDoc => bfilename('XML_TEST','oif_dtypes.xsd'));
End;
then Created a table:
Create table XML_default auf XMLType
then inserted XML like this:
insert into xml_default
values
XMLTYPE
Bfilename ('XML_TEST', 'Test.xml'),
nls_charset_id('AL32UTF8'
Now to my question: Oracle is offering more than one possebility to save XML into its DB. If I import XML like this, is it called CLOB Storage or object relational?
Thanks in advance

Hi ,
I can only give u a few examples here but for the full sytanx and features of this powerful feature u may have to refer to some documentation online or read a book on XML within Oracle Database.
Let me try a few examples here
1) To extract the data from XML document an SQL plus command is available in XML DB. This feature is available from 10G onwards
example : select xmlelement(name,ename) from emp
Output will look like
<NAME>SMITH </NAME>
<NAME> JOHN </NAME>
<NAME> JONES </NAME>
2) CREATE TABLE FAMILIES (F_ID NUMBER(3), F_XML XMLTYPE);
insert into families values(1,xmltype('<XML.....>'));
or
insert into families values(1,''<XML>......' ));
Hope this helps !!!
