Using dbms_xmlsave

Question

I am trying to save contents of xml file into database tables. I know I have to use dbms_xmlsave.insertxml, but it does not allow you to work with multiple tables, so I created a view to join 2 tables together. But when I try to insert into the view I get this error:
ERROR at line 1:
ORA-29532: Java call terminated by uncaught Java exception:
oracle.xml.sql.OracleXMLSQLException: Exception
'oracle.jdbc.driver.OracleSQLException:ORA-01732: data manipulation operation
not legal on this view
' encountered during processing ROW element 1All prior XML row changes were
rolled back. in the XML document.
ORA-06512: at "SYS.DBMS_XMLSAVE", line 91
ORA-06512: at line 31
My xmldatagram looks like this:
<?xml version = "1.0"?>

Hi,
For your XML file I think you just need to enclose XML elemnts in ROWSET AND ROW TAGS - so xml should look like :
<ROWSET>
<ROW>
<DEPT>
</DEPT>
and just pass it as CLOB to dbms_xmlsave.insertXML proc.
I hope it should work.
I am also trying to insert XML file but with a bit complex structure having multiple nested elements.
I am not sure how to transform the external XML file to wrap it in ROWSET/ROW using XSLT. It's mandatory to use ROWSET/ROW tags to be able to insert in oracle tables. I am facing this problem right now. I am using object views to accomplish the purpose but still needs to figure out the way to apply stylesheet to incoming XML file.
If you come to know of any way, pls do let me know also.
Thanks
