What is this
Use third-party tools to close tags

How about this?
I am afraid that your idea cannot solve the problem. Such problems are often caused by abnormalities in the overall structure.
It means that there should be no html tags that span "blocks" when making templates, otherwise it will not only be difficult to maintain but also prone to problems. For example
<code>//a.php
<div>
<h2>Hello</h2>
//b.php
<p>world</p>
</div>
//c.php
require a.php;
require b.php;</code>
c combines a and b to form a completely closed label, but this is not recommended. Your idea is to close a and b respectively through algorithms, but this may invalidate the original css, resulting in abnormal layout, which means that the problem cannot be solved fundamentally. So I suggest you think carefully about the overall solution.
Regular match tag?
