Good afternoon all,
I have a hash containing thousands of lines of text from hundreds of different files.
Every time a certain phrase appears in the hash (in the SSCCE below, "This is"), I want to create a new txt file which prints both the phrase and all subsequent text until we reach the next "This is".
So, for instance, I had hoped that the script below would create six text files (named UserA_1, UserA_2 etc.) where the first file contained the text "This is line 1 from text 1
another line here which should be included in the text file with the above line.", the second file contained the text "This is line 2 from text 1", and so on.
However, although the script below creates the 6 new text files (and names them appropriately), it does not actually print anything into the files.
#!/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 $outfile;
while ($mycorpus{$filename} =~ /This is/g) {
close $outfile if $outfile;
open $outfile, '>', "UserA_$count.txt"
or die "could not open";
$count++;
print {$outfile} $_;
}
}
I have been working on this script for nearly a week, but I can't spot my mistake(s), and thus I would be very grateful for any help.
EDIT:
I probably should have mentioned in my original post that my code here is based on a more basic script that I use to split and print text NOT stored in a hash. This script (reproduced as an SSCCE below) works successfully and returns the desired output.
my $count = 1;
my $outfile;
while (<DATA>) {
if ( my($regex) = /This is/g) {
close $outfile if $outfile;
open $outfile, '>', "UserA$1_$count.txt"
or die "could not open 'UserA$regex.txt' $!";
$count++;
}
print {$outfile} $_;
}
__DATA__
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
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

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>

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).
