In RPE, is it possible to change the content (not attributes) of a DNG artifact.
One answer
No. RPE can only read data (do a GET request) and hence you cannot change the content of DNG artifact.
If you are looking for changing the content in the generated report (document), the answer is Yes. You may refer https://rpeactual.com/2013/01/18/processing-rich-text-in-rpe/
