Out of curiosity, why do you say that the problem has not been solved?

Prior to your claim that "this problem is not solved in both end", I posted to both forums (here at PerlMonks and here at Stack Overflow) a suggestion to check out HTML::Valid.

According to the documentation of HTML::Tidy, you need to have tidyp installed first and tidyp appears to be a fork of tidy and that site indicates that it is the "HTML Tidy Legacy Website". The HTML::Valid module is based on the HTML Tidy project and it does support HTML5.

And I'll take it a bit further. Here's a demonstration of HTML::Valid on the OP's posted HTML/XHTML data.

I created a test.html file with the following content (from the OP):

<?xml version="1.0" encoding="utf-8"?><html xmlns:svg="http://www.w3.o
+rg 2000/svg" xmlns="http://www.w3.org/1999/xhtml" xmlns:m="http://www
+.w3.org 1998/Math/MathML" xml:lang="en" lang="en">
<head>
<link rel="stylesheet" type="text/css" title="day" href="../css/main.c
+ss"/>
<title>Electric Potential and Electric Potential Energy</title>
<meta charset="UTF-8"/>
<meta name="dcterms.conformsTo" content="PXE 1.39 ProductLevelReuse"/>
<meta name="generator" content="PXE Tools version 1.39.69"/>
</head>
<body>
<section class="chapter" ><header><h1 class="title"><span class="numbe
+r">20</span> Electric Potential and Electric Potential Energy</h1></h
+eader>
<section class="frontmatter">
<section class="listgroup"><header><h1 class="title">Big Ideas</h1></h
+eader>
<ol>
<li><p>Electric potential energy is similar to gravitational potential
+ energy.</p></li>
</ol>
</section>
</section>
</body>
</html>
[download]

And here's the Perl code that uses HTML::Valid to check that file:

use strict;
use warnings;

use feature 'say';

use HTML::Valid;
use Path::Tiny;

my $file = 'test.html';
my $content = path($file)->slurp;

my $validate = HTML::Valid->new();
my ($output,$errors) = $validate->run($content);

say "Output:\n$output\n";
say "Errors:\n$errors";
[download]

And here's the output of that script:

Output:
<?xml version="1.0" encoding="utf-8"?>

That shows that HTML::Valid is not having issues dealing with <section> tags and that is also provides line numbers and column numbers as the OP stated here as something that was needed. Unfortunately it looks like HTML::Valid does not have an ignore method that was in the OP's code had that used HTML::Tidy, so the OP may need to write a little bit more code to parse out the messages concerning tags that the OP wants to ignore.

Unless I totally misunderstood what the "problem" was, it looks like HTML::Valid "solves" the "problem".
