Hi,
I have created the following XML file and have used the anonymous pl/sql block to read the XML and load my table.
I got the below error. Kindly let me know how to resolve it.
thanks for your support.

There are plenty of examples in our XML forum (where I moved your topic), just search for "bfilename" and/or "xmltable" in it.

No, you haven't. The code that you posted is invalid in so many ways, missing from clauses, plus signs instead of concatenation, no resemblance to valid xml.

How can you load something that doesn't exist?

What error? Where? I don't see any error.

You need to start over and confirm that one piece at a time works. Make sure you actually have xml data before you try to load it.

There is no need for PL/SQL. Just use a SQL insert statement, but make sure the select that it uses works first, before you try to put that select in an insert.

If you expect help, then you need to post create table and insert statements for sample data used to create your xml data or at least post the created xml data. You should also explain what your ultimate goal is.
