passing path as variable parameter in xmltable

Hi Experts,

I am using xmltable function within a function.
I am passing the column paths as 'employee1\Name\Fname'
I tried using the input parameter just after path keyword in xmltable query but got error as below:

PL/SQL: ORA-01780: string literal required

How to make it possible to pass paths as dynamic variables ?

I don't believe you can pass a dynamic PATH for columns.  You can pass a dynamic XPATH.

Take a look at this example:
drop table tab1 purge;
create table tab1 ( col1 xmltype);

insert into tab1 values('<a><b>Hello</b></a>');


create or replace function myfunc(p_path in varchar2) return varchar2
                retval varchar2(10);

                select myval into retval
                                xmltable (
                                                passing col1
                                                                myval varchar2(10) path '.'

                return retval;

show errors

select myfunc('/a/b') from dual;
