I've to extract a value (Value1) from header file (in the example) and then delete all of it lines in the file.
For example i've a txt file with:
" <Header Begin><?xml version="1.0" encoding="UTF-8"?><header> <comments="Value1: x1_y1, Value2:xyz, Value3:x3">.....
From processor in Nifi i ve thinking about:
1) ExtractText: to save attribute Value1 with it values (x1 and then y1)
2) ReplaceText: to delete all the header and leave only the file.
How can i configure this two processor to do this?
