create table test2
(id int,
country varchar(50))
insert into test1 values (1,'French, China,Japan')
insert into test1 values (2,'Malaysia, Singapore')
insert into test2 values (1,'Japan, China')


WITH extract1 (country_Attributes) AS

country_Attributes.value('/country[1]/Attribute[4]','varchar(25)') AS d
into #temp
FROM extract1;

select country into #temp2 from
(SELECT rtrim(ltrim(colval)) as country
FROM
(SELECT a, b,c,d
