My script calls a sub, Pod::Select::podselect(), which writes the pod sections found in files to a named file or to STDOUT (default).

I want to collect those pod sections in a hash, %podstrings. Is there a way to redirect that output back into my script? Something more elegant than writing to a tempfile and then reading that file back into my hash?

If podselect() returned the string, it would be easy - but it does not, and I don't wish to hack it. 
#!/usr/bin/perl -w

use strict;

use File::Find;
use File::Slurp;
use Pod::Select;
    
my $dir = "h:/temp/TestAppNotes/Pod/";

my %podstrings;
find ( sub {
    return if -d;
    ### I would like to assign
    ### $filestrings{$File::Find::name} = podselect $File::Find::name;
+  

    my $tmpfile = "$dir/tmpfile.txt";    
    podselect {-output => $tmpfile}, $File::Find::name;
    if (-s $tmpfile) {
        $podstrings{$File::Find::name} = scalar read_file($tmpfile)
    }
}, $dir);

for (keys %podstrings) {
    printf "%s   %d\n", $_, -s $_;
}

__END__
