Fwd: NiFi: update attributes with other existing attributes

[Pavan Challa]

Hi,
I would like to know how to update flowfile Attributes in NiFi?

my xml configuration file is as below.


   1. <configuration verbose="false" debugMode="false">
   2.   <dataFlows>
   3.           <dataFlow>
   4.                   <properties>
   5.                           <dept>salary</dept>
   6.                           <version>1.0</version>
   7.                   </properties>
   8.                   <to>
   9.                           <path>d_${dept}/${version}/csv</path>
   10.                  </to>
   11.          </dataFlow>
   12.  </dataFlows>
   13. </configuration>

from LookupAttributes (with XMLFileLookupService), I am able to extract
attributes like dept, version and path like below.

dept: salary

version: 1.0

path: d_${dept}/${version}/csv

I have tried to use updateAttribute and create new attribute called

to-path: ${path}

but to-path is also giving value as d_${dept}/${version}/csv

Can anyone help me to get to-path as d_salary/1.0/csv?
