in reply to Split and print hash based on regex
Here is a possible solution that makes use of the three argument open (with a reference to the filename). This if all the data is in a hash.
Edit: added conditional to print command ('if $outfile')#!/usr/bin/perl use strict; use warnings; #SSCCE: my %mycorpus = ( text1 => "This is line 1 from text 1 another line here which should be included in the text file with the a +bove line. This is line 2 from text 1 This is line 3 from text 1", text2 => "This is line 1 from text 2 This is line 2 from text 2 another line here which should be included in the text file with the a +bove line. This is line 3 from text 2", ); my $count = 1; foreach my $filename (sort keys %mycorpus) { my $outfile; open my $fh, '<', \$mycorpus{$filename} or die $!; while (<$fh>) { chomp; if (/^This is/) { close $outfile if $outfile; my $out = "UserA_$count.txt"; open $outfile, '>', $out or die "could not open '$out' for writing $!"; $count++; } print $outfile $_, "\n" if $outfile; } }
Edit2: The solution offered by tybalt89, Re: Split and print hash based on regex is better than this one. His does not rely on the identifying phase to be at the front of the line of text. The post by jh also is better than this one.
