The following content comes from Nifi within a flowfile
23;22;34;32
I have in that flowfile in attributes a variable that is called a column, which indicates which column is the one I have to keep.
For example, if column is 1, then I have to keep the value of 23, if it is 3, with 34 ....
With what processor can I do it? I'm trying an extractText using regular exprewsiones, but it does not work ...
Thanks Jesus
