in reply to Parsing data into an Array of Hashes

No one's suggested it yet, so I thought I'd try something. I was able to do this without splitting the data. I just looped it through a regex. If your data is all on one line, then you don't even need the outer while loop. Hope this helps.
#!/usr/local/bin/perl -w use strict; use Data::Dumper; my %records; while ( <DATA> ) { chomp; while ( m| (\w+)\s* = \s*([^,]+)\s* |gx ) { $records{$1} = $2; # add to hash } } print Dumper( \%records ); __DATA__ F1=D1, F2 = D2, F3= D3, F4 =D4, F5 = D5
$VAR1 = { 'F2' => 'D2', 'F3' => 'D3', 'F4' => 'D4', 'F5' => 'D5', 'F1' => 'D1' };

[Corion]: And the second rule that I've learned is, that there is no one-off job, so writing a program for it pays off almost immediately. The third rule is to give all my programs numbers and have them reproduce that number in the name of their output files. :)
[Discipulus]: the true part is that also specification change between years.. but well our job is cheap but dont abuse of us.. ;=)
[LanX]: Choroba: do you miss chaos with ties? apply at the US government.. ;)
[ambrus]: Corion: those are good rules.
[ambrus]: Discipulus: oh sure. the input data has different filenames every time I get them.
[ambrus]: the directory structure may be 1, 2, or 3 deep, it may have spaces in the filename or not, it has dates in various format, different keywords for the same meanings, and the dates and other keywords are assembled in various ways.
[Discipulus]: no ambrus by specification i mean for example license per core instead of per socket, so fields are different
