Hi Andy, Thank you for your quick answer and interest.
Actually I tried that but there were still 2 attributes on the flow file. As far as I understand it is by design, I can't set just one attribute, it has at least 2. Am i right? Can I use Route Text Processor instead of Extract Text (I have given my Extract Text configuration at the above) Dou you have comment? -- Sent from: http://apache-nifi-users-list.2361937.n4.nabble.com/
