This is a way you could do it using Template Toolkit. Using a template system allows you to keep the HTML out of your code and will also handle writing the new files for you:

use Template;
my $template = Template->new;
my $tmpl = 'table.tmpl';

my %names;
while ( my $line = <DATA> ) {
    chomp $line;
    my ($name,$item,$answer) = ($line =~ m/^(\w+)\s+(\w+)\s*-\s*(.*)/)
+;
    push( @{ $names{$name} }, { item=>$item, answer=>$answer } );
}
for my $name ( keys %names ) {
    my $table = { title=>$name, rows=>$names{$name} };
    $template->process( $tmpl, $table, "$name.html" )
        || die $template->error();
}

__DATA__
Filename1 Item1 - Answer
Filename1 Item2 - Answer
Filename2 Item1 - Answer
Filename2 Item2 - Answer

This will create two new files "Filename1.html" and "Filename2.html".

The content part of the template file "table.tmpl" would look like this:

<h1>[% title %]</h1>

<table>
[% FOREACH row IN rows %]
    <tr>
        <td>[% row.item %]</td>
        <td>[% row.answer %]</td>
    </tr>
[% END %]
</table>

Obviously, you need to add the html and body tags around this, and you can also add CSS and other static elements.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• 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).
