符合 HTML5 的 HTML 过滤器

php tidy 扩展可以配置为识别 html5 标签。http://tidy.sourceforge.net/docs/quickref.html#new-blocklevel-tags

我正在使用 wordpress 的修复程序，但也许这也可以帮助您（至少对于数组部分）

也：

http://code.google.com/p/html5lib/Python 和 PHP 的实现 基于 WHATWG HTML5 规范的 HTML 解析器，最大 与主要桌面 Web 浏览器的兼容性。

Gallery Role 有一个基于 HTMLPurifier 的实验性 HTML5 解析器：

HTMLpurify 有此配置以允许更新的 HTML5 标记。

我知道这个话题真的很老，但由于它仍然相关，我决定做出回应。特别是当情况自最初提出问题以来发生了变化时。

您可以使用 https://github.com/xemlock/htmlpurifier-html5，它使用符合规范的 HTML5 元素和属性定义来扩展 HTML Purifier。

用法和原来的HTML净化器差不多，你只需要换成：HTMLPurifier_ConfigHTMLPurifier_HTML5Config

$config = HTMLPurifier_HTML5Config::createDefault();
$purifier = new HTMLPurifier($config);

$clean_html5 = $purifier->purify($dirty_html5);
