Greetings Monks,

I'm parsing a file that's tab-delimited, except it has a bunch of extra white space around the values that I'd like to remove. I can't just use split on white space, because there's mixed values (some floats, that I'd like to remove the white space from, and some strings that can have white space).

My first attempt was this:

#!/bin/perl

use warnings;
use strict;
use Data::Dump qw(pp);

while(<DATA>){
   my @points = map{ s/\s+// } split("\t", $_);
   print "\n\@points =\n", pp \@points;
   #More code here
}

__DATA__
   0.000           12      0.232           13      11      text that c
+an have space
   1.000           13      0.534           14      12      More text t
+hat would be ok
   2.000           14      0.876           15      13      yet more te
+xt

But I get this:

@points =
[1]
@points =
[1]
@points =
[1]

Which definitely makes me think I have a context error going. What's the appropriate way to do this? (I know that the s/\s+// will remove the white space in the text too, I'm ok with that for now, I'd like to remove it from around the floats first.)

Effective use of map has always been my Everest, and with your help I will summit it this time!


Thanks in advance for your wisdom!
