Insert Insert XML file into multiple records in Oracle Database

Question

I would like to find out if it is possible to insert a single XML file into multiple records or tuples in a Oracle database table. I have a single XML file which is at multiple levels. The meta data for the levels are common and each level can have meta data of their own in addition. I do not have any meta data field which will uniquely determine whether the data belongs to Root level, Intermediate level or at the document level. Is there any way I can determine which level the meta data belongs to and thereby make a corresponding entry into the database table tuple? For example I could have an attribute called level which is going to be present only in the database table and not in the XML file. If level=1 then it corresponds to "Root" meta data, if level=2 then it corresponds to "Intermediate" level and if level=3 then it corresponds to meta data at document level. I need a way to calculate the value for level from the XML file and thereby insert the meta data element into a tuple in a single table in Oracle.

Hi,
extract your xml and then you can use insert all clause.
here's very small example on 10.2.0.1.0
SQL> create table table1(id number,val varchar2(10));
Table created.
SQL> create table table2(id number,val varchar2(10));
Table created.
SQL> insert all
  2  into table1 values(id,val)
  3  into table2 values(id2,val2)
  4  select extractValue(x.col,'/a/id1') id
  5        ,extractValue(x.col,'/a/value') val
  6        ,extractValue(x.col,'/a/value2') val2
  7        ,extractValue(x.col,'/a/id2') id2
  8  from (select xmltype('<a><id1>1</id1><value>a</value><id2>2</id2><value2>b</value2></a>') col from dual) x;
2 rows created.
SQL> select * from table1;
        ID VAL                                                                 
         1 a                                                                   
SQL> select * from table2;
        ID VAL                                                                 
         2 b                                                                    Ants
