Grep netlist and cell name from file and display in string field

Hello Andrew,

I am facing one issue as i have created one string field box with browse option it will pickup the setup file....Also there are two more string boxes made ..i.e netlist string field and cell string filed.

setup file consists of --

Source "netlist.tcl"
cell "chklist"

Now i want that when user selects any setup file from browse option automatically in netlist string field it get filled as it takes the realpath of netlist.tcl(source) from setup file ...same in cell string boxes gets filled as it takes the cell
i.e chklist from setup file.

how can i achieve that..
any example or guidance will be appreciated.
ouput will be something like this-
