I didn't follow the logic you are implementing. However, the syntax error can be removed by specifying the column name as shown below:

....
where table_name = 'dim_employee') c
for xml path(''), type ) v(alais_name)

looks like attempt is to generate a column list from columns in dim_employee table but didnt understand purpose of replace logic though
