thanks.

Seems the oracle version is the problem for me then. I get

SQL> exec Zbis_Users_Load
BEGIN Zbis_Users_Load; END;

*
ERROR at line 1:
ORA-20100: Error occurred while parsing: Start of root element expected.
ORA-06512: at "SYS.XMLPARSER", line 22
ORA-06512: at "SYS.XMLPARSER", line 103
ORA-06512: at "ADDPM.ZBIS_USERS_LOAD", line 35
ORA-06512: at line 1
