I have a CSV file where the first few lines are a summary of the report
parameters that were used to generate it. I want to strip these off in NiFi.
I've considered using a RegEx to match the {N} top lines, but am wondering of a
Groovy script might be a better option? I want to keep the file intact, so
splitting it by line ending and routing all of the lines through a
RouteByAttribute seems excessive.I've never built a Groovy script, any examples on how I might go about this? Thanks, Peter
