Here is a program I threw together after surfing the Internet.

use strict;
use warnings;

use HTML::HTML5::Parser qw();
use HTML::HTML5::Writer qw();
use XML::LibXML::PrettyPrint qw();

print HTML::HTML5::Writer->new(
    start_tags => 'force',
    end_tags => 'force',
)->document(
    XML::LibXML::PrettyPrint->new_for_html(
        indent_string => "\t"
    )->pretty_print(
        HTML::HTML5::Parser->new->parse_string(
            q[<meta content="J K Rolling" name="Author" />
<meta content="Harry Potter and the Philosopher's Stone" name="title" 
+/>
]
        )
    )
);
  
# This prints:
# <!DOCTYPE html><html>
#         <head>
#                 <meta content="J K Rolling" name=Author>
#                 <meta content="Harry Potter and the Philosopher's St
+one" name=title>
#         </head>
#         <body></body>

The order of the meta content is the way you want it.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
