In general, this kind of problem is very easy to solve in Perl, but your data poses a few problems.
- You have multiple columns with the same name
- You have commas in your data
You will need a more sophisticated data model than a simple hash, or a method for coming up with unique hash keys. The following is therefore simplistic but shows what can be done.
use strict;
use warnings;
chomp(my $datafile = shift || 'data.file');
my $outputfile = 'output.file';
my @keys_in_display_order = qw/Activity Status Valuation/;
my (%hash);
open my $ifh, '<', $datafile;
open my $ofh, '>', $outputfile;
printf $ofh "%s\n", join '|', @keys_in_display_order;
while(<$ifh>) {
next unless $_;
if (/^$keys_in_display_order[0]/) {
print_it();
%hash = ();
}
$hash{$1} = $2 if (m/(.+):(.+)$/);
}
print_it();
close $ifh;
close $ofh;
sub print_it {
return unless (%hash);
printf $ofh "%s\n", join '|', @hash{@keys_in_display_order};
}
cat output.file

But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us. Romans 5:8 (NASB)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
