in reply to array of hashes, categorized by array index
Why "name" the fields. They are indexed numerically, so use the indexes to index your report array.
The following is a dump of @report. It shows that (from the 3 line sample supplied) field[0] contains 2x'483' and 1x'769'; field[1] contained 1 each of 3 values:'DS', 'OS', 'XO'; and so on.
C:\test\primes>..\junk83 [ { 483 => 2, 769 => 1 }, { DS => 1, OS => 1, XO => 1 }, { "dx-14" => 1, "dx-32" => 2 }, { 1 => 2, 5 => 1 }, { charles => 1, james => 1, sully => 1 }, { list3 => 1, list4 => 1, nolist => 1 }, { "23.456.12.7" => 1, "aardvark.com" => 1, "widgets.com" => 1 }, { "ty-off" => 1, "ty-on" => 2 }, { "lx-on" => 3 }, { B => 1, C => 1, V => 1 }, { "01" => 2, "07" => 1 }, ]
Code to produce the above output:
#! perl -slw use strict; use Data::Dump qw[ pp ]; my @report; while( <DATA> ) { my @f = split ' ', $_; for my $field ( 0 .. $#f ) { $report[ $field ]{ $f[ $field ] }++; } } pp \@report; __DATA__ 483 OS dx-32 1 charles list4 aardvark.com ty-off lx-on C 01 483 DS dx-14 1 james list3 23.456.12.7 ty-on lx-on B 01 769 XO dx-32 5 sully nolist widgets.com ty-on lx-on V 07
With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
