[QUOTE="Li Chen, post: 4613130"] Hi all, I need to read a CSV file with csv library. And I tried the example from the library. require 'csv' CSV::Reader.parse(File.open('test.csv')) do |row| puts row # break if !row[0].is_null && row[0].data == 'stop' end Here is what I got: #<CSV::Cell:0x2b7c350> ... #<CSV::Cell:0x2b78b4c> I wonder why I can't print out the string/row itself instead of the address of the string/row. Thanks, Li [/QUOTE]
