Hi All,

How to remove {} from output 

I am using below query 

select (xpath('//Grading_Automated',(select xmlgrading from km_course_mast where id='100000'))) from km_course_mast where id='100000'

The out is below 

"{"<Grading_Automated>
 
</Grading_Automated>"}"

 
The xpath return type is of type array. PG returns the array data, enclosed in "{}". If you want to remove these "{}" braces, then use either array_to_string(xpath(.......)) or trim the braces from the xpath output.
