Trouble executing data found on TABLE: exe_sel_dttime_xml (COLUMN: QUERY)

Question

Hello,
I want to execute using EXECUTE IMMEDIATE the data found on a table
exe_sel_dttime_xml
The following code inside a PLSQL procedure constantly gives me coding problems(therefore not working as it should!!):
BEGIN
FOR r
IN (SELECT QUERY INTO v_toexecute FROM exe_sel_dttime_xml)
LOOP
EXECUTE IMMEDIATE v_toexecute;
END LOOP;
END;
Basically what this code is supposed to do is execute each of the data found inside the COLUMN: [QUERY] found on the TABLE: [exe_sel_dttime_xml]
ie,
SQL> r
1 select * from exe_sel_dttime_xml
2*
QUERY
SELECT COL_TNAME, DEVICE_DTTIME
INTO table_dttime(COL_TNAME, COL_DTTIME)
FROM t_xml_01;
SELECT COL_TNAME, DEVICE_DTTIME
INTO table_dttime(COL_TNAME, COL_DTTIME)
FROM t_xml_02;
SELECT COL_TNAME, DEVICE_DTTIME
INTO table_dttime(COL_TNAME, COL_DTTIME)
FROM t_xml_03;
SELECT COL_TNAME, DEVICE_DTTIME
INTO table_dttime(COL_TNAME, COL_DTTIME)
FROM t_xml_04;
SELECT COL_TNAME, DEVICE_DTTIME
INTO table_dttime(COL_TNAME, COL_DTTIME)
FROM t_xml_05;
SELECT COL_TNAME, DEVICE_DTTIME
INTO table_dttime(COL_TNAME, COL_DTTIME)
FROM t_xml_06;
Remember,
I need this to work using the following:
+ EXECUTE IMMEDIATE
+ Querying the data from table: exe_sel_dttime_xml
(ie, SELECT QUERY INTO v_toexecute FROM exe_sel_dttime_xml)
All (and any) help is appreciated

first thing, when writing cursor for loop, the select statement does not have to contain the INTO clause.
for rec in (select ename from scott.emp)
loop
  dbms_output.put_line(rec.ename) ;
end loop ;Next, can you execute the select statements stored in the table exe_sel_dttime_xml at the SQL*Plus prompt?
if you cannot, you cannot do execute immediate on them.
if the table_dttime is a table in the database into which you are inserting the data selected from the table t_xml_01, then it should be coded as a
insert into ... select ...
statement.
explain in detail what you are trying to do and someone can help you.
