Parsing options - new 'Read File' component

Hi,
i am currently working on some project where i am linking very simple outputs from processing to GH via a text file.
right now i am using one text file for each value i'd like to read in GH (one for X, one for Y, one for Z etc...)
i am doing this because i haven't figured out how to read Tab or Comma separated values

by double clicking on the new Read File component, there is room for some Parsing Options, can somebody help me reading a text file where on each line, i have 3 values, separated by a tabulation, i would like to store these into 3 lists of variables.

thanks a lot !

i join the text file i'd like to read into GH - on each line, the first 2 values are an X and Y coordinate, and the 3rd value is the radius of the circle in (x,y)
