    I'm trying to build an HTML-altering program using HTTP::TreeBuilder,
    but am having a problem dealing with comments. I have "savecomments"
    turned on, and the comments are being put into the tree, but they're all
    dumped in at the end, between </body> and </html>.

    The additional error with DOCTYPE is documented, and I can deal with it,
    but the destruction of the context of comments is ruinous for my purposes.

    Current program:

    use strict;
    use warnings;
    use HTML::TreeBuilder;
    my $tree = HTML::TreeBuilder->new();
    $tree->store_comments (1);
    $tree->store_declarations (1);
    $tree->parse_file ('text.html');
    $tree->elementify;
    print $tree->as_HTML;
    $tree->delete;

    Current input:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
    <!--This is a comment before html-->
    <html>
    <!--This is a comment before head-->
    <head>
    <title>Test</title>
    </head>
    <body>
    <p>This is it.</p>
    </body>
    </html>
    <!--This is a comment after html-->

    Current output:

    <html><head><title>Test</title></head><body><p>This is
    it.</body><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0
    Transitional//EN"><!--This is a comment before html--><!--This is a
    comment before head--><!--This is a comment after html--></html>
