If the data sample that you provided in this reply above is (part of) the content of a single data file, then you should have multiple lines printed for each file. I would try something like this (although actually, I think it would be worthwhile to try a real HTML parsing module, as recommended by others above):

use strict;

opendir( DIR, "data" );  # use a variable if you need to handle differ
+ent values
my @files = grep /\.txt$/, readdir( DIR );
closedir DIR;

warn scalar @files . " files to read\n";
open( OUT, ">", "list.txt" ) or die "list.txt: $!\n";

for my $file ( @files ) {
    local $/;    # sets $/ to undef (locally)
    open( IN, $file ) or warn "$file: $!\n";
    $_ = <IN>;  # reads entire file because $/ is undef
    close IN;

    while ( m{<a href=.*?>(\w+)<.*?class="report"[^>]+>(\w+)<}sg ) {
        print OUT "$file -- $1  -- $2\n";
    }
}
