Re^9: constructing a tree from csv file

To avoid the warnings, just do not print anything if the relation is not defined:

    print " = ", $path_string, ', ', $group{$path_string} // q();

Choroba what if I dont want those lines which dont have a group (from the group hash) to be "even" printed ? For example a line which has relation : E.E.E.P.Pl doesnt have a corresponding key-value pair in the group hash, so I would like this complete row to not even get printed. I guess something has to be added in this line `print " , ", $path_string, ', ', $group{$path_string};`	[reply] [d/l]

Use a condition: `print " , ", $path_string, ', ', $group{$path_string} if exists $group +{$path_string};` [download] لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l]
