How to read and save the following XML-Doc?

Question

Hi all,
I have a XML-Document:
<root>
<employees>
<emp1>
<ename>Test1</ename>
<empno>1</empno>
<sal/>
<ord>
<item>1</item>
</ord>
</emp1>
<emp2>
<ename>Test2</ename>
<empno>2</empno>
<sal>1000</sal>
<comm>200</comm>
<ord>
<item>3</item>
</ord>
</emp2>
</employees>
</root>
This should I save in the databse table:
CREATE TABLE XML_DOC
ID NUMBER(38),
FATHERTAG NUMBER(38),
TAGNAME VARCHAR2(250),
TAGCONT VARCHAR2(4000)
And tha data should be saved in the following format:
=======================================
| ID | FATHERTAG | TAGNAME | TAGCONT|
| 1 | | root | |
| 2 | 1 | EMPLOYEES | |
| 3 | 2 | EMP1 | |
| 4 | 3 | ENAME | Test1 |
| 5 | 3 | EMPNO | 1 |
| 6 | 3 | SAL | |
| 7 | 3 | ORD | |
| 8 | 7 | ITEM | 1 |
| 9 | 2 | EMP2 | |
Has anyone any Idea how to realize it?
Regards

Leonid,
Why don't you just store the xml document in the database as an xmltype? You could then build a view over the object-relational table to pull the data out into the format you want.
The following code Example is from one of my favorite DBA's Johnathan Gennick and can be found at this link.

CREATE VIEW cd_master (Title, Artist, Website, Description) AS
SELECT extractValue(value(x),'/CD/Title'),
extractValue(value(x),'/CD/Artist'),
extractValue(value(x),'/CD/Website'),
extractValue(value(x),'/CD/Description')
FROM CD331_TAB x;
