This one way to delete leading and trailing spaces from CSV input.
<c>
#!/usr/bin/perl -w
use strict;
use Text::CSV;
use Data::Dumper; # a core module
use Data::Dump qw(pp);
open my $io, '<',
\q{"My Company","Gavin","Henry ","ghenry@ghenry.co.uk"," 1.00"};
my $csv = Text::CSV->new(); # nothing "fancy" needed here
# defaults are fine
while ( my $row = $csv->getline($io) )
{
my @fields =map {
s/^\s*//; #delete leading spaces
s/\s*$//; #delete trailing spaces
$_; #this is the "return value" from map
#map returns the value of the last
#statement - without this $_; you
#get the zero or non-zero scalar value
#of the last s/// statement
} @$row;
print "Using pp from Data::Dump...\n";
print pp \@fields;
print "\n";
print "Using Dumper from Data::Dumper...\n";
print Dumper \@fields;
print "\n";
print "5th field is $fields[4]\n";
}
__END__
Prints:
Using pp from Data::Dump...
["My Company", "Gavin", "Henry", "ghenry\@ghenry.co.uk", "1.00"]
Using Dumper from Data::Dumper...
$VAR1 = [
'My Company',
'Gavin',
'Henry',
'ghenry@ghenry.co.uk',
'1.00'
];
5th field is 1.00
