By using Extract Text processor we are able to work only on flowfile content.

Use UpdateAttribute processor as this processor meant for updating the values of Existing attributes (or) add new attributes based on the existing/new values.

We can also use NiFi expression language in UpdateAttribute processor for regex use replaceAll .. etc string manupulation functions and apply your regex on the attributes of the flowfile.
