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
