( #3333=superdoc: print w/replies, xml ) Need Help??

Consider the following:

#!usr/bin/perl use strict; use warnings; $/ = "\n1="; open my $fh, '>', '/a/b/c/perl/dl_parser/logData.txt' or die $!; while (<>) { my @fields = split /\n/; s/^[1-6]=// and s/\s+$// for @fields; print $fh ( join ',', map qq/"$_"/, @fields[ 0 .. 5 ] ) . "\n"; } close $fh;

For each csv line, your script will open, write to, and then close the logData.txt file. When done, that file will have only one line, viz., the last one written to it. The above will write all csv lines to your file, since the open and close statements are outside the while loop. Additionally, note that open is using a lexically-scoped file handle (my $fh) and that it is a three-argument open.

Have added two items to the script. The first is an additional substitution, since there was a space at the end of the last three fields. The second, a map statement, encloses each field within quotations, since the first data field contains a comma (remove the map qq/"$_"/, if you want the date and time to be treated as separate csv fields).

Hope this helps!
