How to replace entire Flowfile content?

Question

I want to start with one Flowfile body text and then completely replace it during the course of my process. How do I replace the entire Flowfile content with some new static content?

There are many processors which can manipulate the content of a flowfile, but the simplest processors would be GenerateFlowFile (to create a flowfile with custom static/dynamic text) and ReplaceText (to replace the content of an existing flowfile). For ReplaceText, you can use a matching regex pattern for Search Value of ^(.*)$ to match all characters in the incoming flowfile content and replace it with whatever static (or dynamic via Expression Language) content you like.
