PHP DOMDocument errors/warnings on html5-tags
I've been attempting to parse HTML5-code so I can set attributes/values within the code, but it seems DOMDocument(PHP5.3) doesn't support tags like <nav> and <section>.
Is there any way to parse this as HTML in PHP and manipulate the code?
Code to reproduce:
<?php
$dom = new DOMDocument();
$dom->loadHTML("<!DOCTYPE HTML>
<html><head><title>test</title></head>
<body>
<nav>
<ul>
<li>first
<li>second
</ul>
</nav>
<section>
...
</section>
</body>
</html>");
Error
Warning: DOMDocument::loadHTML(): Tag nav invalid in Entity, line: 4 in /home/wbkrnl/public_html/new-mvc/1.php on line 17
Warning: DOMDocument::loadHTML(): Tag section invalid in Entity, line: 10 in /home/wbkrnl/public_html/new-mvc/1.php on line 17
Answer
No, there is no way of specifying a particular doctype to use, or to modify the requirements of the existing one.
Your best workable solution is going to be to disable error reporting with libxml_use_internal_errors:
$dom = new DOMDocument;
libxml_use_internal_errors(true);
$dom->loadHTML('...');
libxml_clear_errors();
