Decompose ANSI X12 transmission into individual documents.

use strict; use warnings; use Data::Dumper; my $ediFile = shift; my ($contents,$delim,$term,$txnCount,@transactions); { $/ = undef; open my $ifh,'<',$ediFile; $contents = <$ifh>; } ($delim,$term) = $contents =~ m/^ISA(.).{101}(.)/; $delim = quotemeta($delim); @transactions = $contents =~ m/(ST$delim.+?SE$delim\d+$delim\d+$term)/ +gs; ($txnCount) = $contents =~ m/${term}GE$delim(\d+)/; die "Parse error - transaction counts wrong" if ($txnCount != scalar @transactions); foreach my $transaction (@transactions) { # put into useful form for processing my @segments = split /$term/,$transaction; my ($segCount) = $transaction =~ m/${term}SE$delim(\d+)/; die "Parse error - segment counts wrong" if ($segCount != scalar @segments); my ($process_this); map { push @$process_this, [split /$delim/,$_] } @segments; print Dumper(\$process_this); }
