That certainly did the trick!! Nice one. So now, I've been playing around with the logic behind skipping duplicated orders within the file... and of course, having issues with it...

Using the same script and data, and keeping in mind that orders, if duplicated, will always (I'm pretty certain) be duplicated in order - ie. an order will be replicated 3 or 4 or more times, and then the report moves on to a different order.

Sorry for the long bit of code here, but figured it easiest to show you what I'm trying :

use strict; use warnings; use Data::Dumper; use Spreadsheet::WriteExcel; # Place a filename into $recordsFile to read Orders from that file # else the Orders below __DATA__ will be used for demo purposes #my $recordsFile = 'finished_report_sample.txt'; my $recordsFile = ''; my ( @records, @orders ); my $recSeparator = 'Order ID:'; # Orders will initially be array elements 1 .. n in @orders; element 0 + is initially the first page header { # Set the record separator local $/ = $recSeparator; # If there's a file name, try to read from that file if ($recordsFile) { open my $fh, '<', $recordsFile or die $!; @records = <$fh>; close $fh; } # End If else { @records = <DATA>; } # End Else } # End preparatory loop # Remove the first page header shift @records; # Add Order ID: back into each record for later matching $_ = "$recSeparator$_" for @records; ########## Added for writing to Excel # Open a new xls file then create a sheet my $workbook = Spreadsheet::WriteExcel->new('distlist.xls'); my $worksheet= $workbook->add_worksheet(); # Write headings $worksheet->write(0,0,'Fiscal Year'); $worksheet->write(0,1,'Vendor'); $worksheet->write(0,2,'PO Number'); $worksheet->write(0,3,'Orderline'); $worksheet->write(0,4,'Title'); $worksheet->write(0,5,'ISBN/ISSN'); $worksheet->write(0,6,'# copies for Title'); $worksheet->write(0,7,'Distribution'); $worksheet->write(0,8,'Date Received'); $worksheet->write(0,9,'Date Loaded'); $worksheet->write(0,10,'Number of Copies'); # Initialise spreadheet counters my $row=1; my $column=0; # Set this up ready for checking for duplicate orders my $previousOrder=""; # Iterate through each record (Order) for my $record (@records) { my %hash; # Treat the record string like a file, opening it for reading open my $sh, '<', \$record or die "Unable to open record string: $ +!"; # Read the string like a file, one line at a time now while (<$sh>) { $hash{orderID} = $1 if !defined $hash{orderID} and /Ord +er ID:(\S+)/; $hash{fiscalCycle} = $1 if !defined $hash{fiscalCycle} and +/cycle:(\d+)/; $hash{vendorID} = $1 if !defined $hash{vendorID} and /Ve +ndor ID:(\S+)/; $hash{requisitionNum} = $1 if !defined $hash{requisitionNum} a +nd /\s+(\d+).+requisition/; $hash{copies} = $1 if !defined $hash{copies} and /copi +es:(\d+)/; $hash{'ISBN/ISSN'} = $1 if !defined $hash{'ISBN/ISSN'} and +m{ISBN/ISSN:(\S+)}; $hash{title} = $1 if !defined $hash{title} and /Title +:(.+)/; # CHeck to see if it's a repeat order, skip if it is. my ($hashReference) = \%hash; if (($previousOrder eq $$hashReference{orderID}) && ($previousOrde +r ne "")) { print "Order: $previousOrder HashOrder: $$hashReference{o +rderID} \n"; print "Order already processed. Skipping...\n"; last; } # End If else { $worksheet->write($row,0,$$hashReference{fiscalCycle}); $worksheet->write($row,1,$$hashReference{vendorID}); $worksheet->write($row,2,$$hashReference{orderID}); $worksheet->write($row,3,$$hashReference{requisitionNum}); $worksheet->write($row,4,$$hashReference{title}); $worksheet->write($row,5,$$hashReference{'ISBN/ISSN'}); $worksheet->write($row,6,$$hashReference{copies}); $previousOrder = $$hashReference{orderID}; # $row+=1; # Distributions started? if (/Distribution--/) { # Save the current record separator my $oldRecSeparator = $/; # Set a new record separator local $/ = 'Distribution--'; # Read the string like a file, a distribution 'chunk' +at a time while (<$sh>) { #I realise this hashing is now superfluous, with data bein +g written # direct to Excel, but am keeping changes to a minimum until + I get # the overall functionality correct. my %tempHash; ( $tempHash{holdingCode} ) = /code:(\S+)/; ( $tempHash{copies} ) = /copies:(\d+)/; ( $tempHash{dateReceived} ) = /received:(\S+)/; ( $tempHash{dateLoaded} ) = /loaded:(\S+)/; $worksheet->write($row,7,$tempHash{holdingCode}); $worksheet->write($row,8,$tempHash{dateReceived}); $worksheet->write($row,9,$tempHash{dateLoaded}); $worksheet->write($row,10,$tempHash{copies}); $row+=1; push @{ $hash{distribution} }, \%tempHash; } # End While # Restore the old record separator $/ = $oldRecSeparator; } # End If } # End Else } # End While # Work with the filled-in %hash by sending a reference to it to a +subroutine # This is a complete record # writeToSpreadSheet( \%hash ); # print Dumper \%hash; # Done 'reading' the string close $sh; } # End For - last of the loops $workbook->close(); # Printing in a subroutine's not a good idea, but done here only to sh +ow how to access the hash #sub writeToSpreadSheet { # my ($hashReference) = @_; # # The $$ notation dereferences the hash reference # print $$hashReference{vendorID}, "\n"; # # The @{} notation deferences the array reference; the arrow opera +tor deferences to get hash value # for my $distribution ( @{ $$hashReference{distribution} } ) { # print $distribution->{holdingCode}, "\n"; # } # # print "\n"; #} __DATA__ List of Distributions Produced Tuesday, 9 October, 2012 at 1:38 PM Order ID:PO-9999 fiscal cycle:21112 Vendor ID:VEND99 order type:SUBSCRIPT 15) requisition number: copies:9 call number:XX(9999999.999) ISBN/ISSN:9999-999X Title:Item title here.

Now, when I run this, somehow $previousOrder is getting a value in it at the "if" logic check, even though the logic check is the first time the variable is seen after it's initialised as ""... as you can see from the output of the first print command.

The other thing I don't understand from this outcome, is that the resultant XLS file has only 2 fields (as well as the headers) written to it - the fiscal year and PO number. I would have thought that, if it made it to the section that writes the PO stuff at all, it would write it all - I don't understand how it can only write part of it?

There's also an issue with the XLS file itself for some reason - giving an error when opening it... but I'm off to research that one myself now while I wait for suggestions on what I've stuffed up with my logic for the duplication check :)
