SQL & PL/SQL :: Check If Element Present In Defined Column Of Cursor?

i want to produce a function who return XmlType element if she checks that a parameter (that i passed to here is contained in a row in a defined table)

for example

create table sec_form(
form_code VARCHAR2(8)
, sec_code VARCHAR2(5)
) ;
insert into sec_form values ('CSA','section1');
insert into sec_form values ('CSA','section2');
insert into sec_form values ('CSA','section3');

then i got my function

create or replace function checkIfSectionEnabled (elem XmlType,name_section varchar2)
return XmlType
is v XmlType;
CURSOR myCursor IS select * from sec_form where form_code = 'CSA';
begin
open myCursor;
loop

[code]....

now i'm gonna call the function (elem XmlType,name_section varchar2) and pass here "section1" for example ; and she must return me my xmltype element if she find "section1" finds section1 present;

when i try t compile i got:

Error(18,13): PL/SQL: Statement ignored
Error(18,26): PLS-00225: subprogram or cursor 'MYCURSOR' reference is out of scope
