pnsreee has asked for the wisdom of the Perl Monks concerning the following question:

Hi All, <p. How can i get columns from cvs file into an array. The CSV file is a dynamic file.

      You should also check the returned status when you parse a line:

      my $csv = Text::CSV_XS->new( { binary => 1 } ); my $status = $csv->parse($line); # parse a CSV string into fie +lds

      Occasionally, you'll encounter an invalid CSV line and you'll definitely want to handle it. If there are any embedded binary chars, you'll want to set the binary flag when you create the $csv object as I did above.

      Hi Joost, It is csv file. I want expresion with out using Text::xSV or Text::CSV_XS.

        Just don't come back whinging when you have data with embedded commas or newlines and the quick hack no longer works. You may get away with it this time, but n months down the road someone (possibly even yourself) will be swearing under their breath at you as they clean up the mess.
