Thank you for your workflow. It’s seems to work, but I have two difficulties.
As I said, I’am working with muliple columns and I have to select my columns in the Column Splitter Node.
So I tried to use Regex selection, but I don’t know how to reverse my selection with the Regex. Instead to having my selection in the Top, it goes on the bottom.
The regular expression used is :
(.*)(Price $.*|Size.*|Target.*) and I tried to reverse this selection by using the ^ caracter. But I don’t know how to use correctly with multiple excluded parts.
Finally the very important thing is that I need to have in the output the columns in the same position since the begining. And when I use a Columns Splitters, all columns are only selected if they have a point (price, size …). So these columns should go back to the original files at the same position.
If it’s not clear, do not hesitate to ask me for clarification.
Again, thank you very much for your help.
