How to Evaluate attribute (output of Invoke Http which is in JSON format)

This attribute value contain a Json in the following format 

 {

    location : { FileSource :  "X" ,  URL : "Y"}

} 

From this attribute value (Json), I need to extract File Source and URL and put it into another attribute with the same name.

Note : Flow file Content should remain as it is.

Any Pointer ..??

Thanks for Reply. 

Solution you have provided will work with content of flow file and not with the attribute.  EvaluateJsonPath is use to evaluate the JSON present in flow file content. 

In my case , I have JSON present as attribute and not as content of flow file.

I got the Solution.

Use UpdateAttribute processor and Expression Language. 

Here "SignedURL" is the attribute (containing complex Json) and from that I fetch particular Key value using Expression Language (JSONPATH)
