hi there,
i want a fancy way of splitting a pipe delimetered string that will ignore the first blank value to the array.

print "start\n";

$string = '|one|two|three|four';


my @array = split /\|/,$string;

foreach (@array)
{
    print "string:$_\n";

}

 print "end\n";


gives:
start
string:
string:one
string:two
string:three
string:four
end

i want:
start
string:one
string:two
string:three
string:four
end

ie, get rid of first pipe..

many thanks
Peewee

You can delete the first value with "shift":

my @array = split /\|/,$string;
shift @array;

Hello-
Does something like this work?

my @array = split /\|/,$string;
$removed = shift(@array);
foreach (@array)
{
   print "string:$_\n";

}

print "end\n";

Or why not just do:

$string =~ s/^\|//g;
$string = '|one|two|three|four';


my @array = split /\|/,$string;

foreach (@array)
{
   print "string:$_\n";

}

print "end\n";

to remove that first empty field. If the field is not empty, it won't do anything.
