I have a file which is having record like this: 
mod_name modname
net_name netname1
      pin pinname1 pinlayername1 pin_coordinates1;
      pin pinname2 pinlayername2 pin_coordinates2;
      .
      .
      .
      .
end net
net_name  netname2
      pin pinname56 pinlayername56 pin_coordinates56;
      .
      .
      .
end net
.
.
.
.
.
end mod

[download]
Now the problem is to populate an object for this file so as on demand for net it shows all the net names, and after taking one net entered it shows all its pinnames and after taking one of its pinname it shows rest pin data like pinlayername and pin_coordinates for that paticular pin.

Would you please suggest me by writing the code that how can i solve this problem?   One thing to remember that don't hardcore any net or pin name!
