Should I create table before insert xml files

Question

Hi,,,
I am developing a application that insert various xml files
into oracle8i dbms..
So, I am studying Oracle XML SQL Utility and I understood that
I should create appropriate tables suit for the XML files..
(tag <--> table column name...) before insert them to the dbms.
But In my project, the xml file is not fixed.
And new XML files (new tag name, new DTD required) can be
generated by the end user.
Is there any solution??? create table suit for xml
automatically..
And...
How can I create table to insert the following xml file..
<univ>
<college name="engineering">
<department name="electronic">
<student id="11">
<math> 100 </math>
<english> 90 </english>
</student>
</department>
</college>
<college name="law">
<department name="law">
<student id="55">
<math> 90 </math>
<english> 100 </english>
</student>
</department>
</college>
</univ>

Hi,
One more thing is that, you can use XSLT to transform any
document that you get into a canonical representation that u can
then use to put into the database.
For example, if the user gave,
<univ>
<college name="eng">
<...>
</college>
</univ>
you can then use XSLT to transform it into all-element form,
such as,
<univ>
<college>
<name>engineering</name>
</college>
</univ>
and use OracleXMLSave to put it into the database. Also if you
have structured XML elements you can map them nicely into object
types in Oracle 8.
Regarding creating the table, for the exampe that you showed,
you can create an object type column for storing it,example,
CREATE TYPE college_type AS OBJECT
name VARCHAR2(50),
dept department_type,
CREATE TYPE department_type AS OBJECT
name VARCHAR2(40),
CREATE TABLE univ_tab ( college college_type);
You could have also created object views over multiple
relational tables and achieved the same.
