If the content of your FlowFile is just ascii text you can use the ReplaceText processor to edit that content. You would configured this processor with a Java regular expression that would single out "2017" in to a set of capture groups. The replacement text value would use some of those capture groups and your new value.


Here is a online regex tester:

Using a FlowFile with just "Thu, 14 Sep 2017 00:00:00 -0000", i configured a ReplaceText processor with:
Search Value: (.*?, \d{1,2} \w{3}) (\d{4}) (.*)$ . <--- This creates 3 capture groups (capture group 2 is the "2017")

Replacement Value: $1 2019 $3 . <--- sets a replacement value of (capture group 1)(space)(2019)(space)(capture group 3)


Thank you,
