Looping in text processing


I have loop problem in the project development. Instead using Java snippet on each column, how can I use Loop Start and Loop End to use just one Java snippet but itterate multiple column in one node.

Picture of problem is at this link:  http://bit.ly/1fFzVh6 




there is the "Column List Loop Start" node to loop over columns, which i think is the best solution for this setting. An other way would be to transpose the table and loop over the rows (which have been columns before) but you may loose type and name information of the previous columns.

Cheers, Kilian
