有没有一种简单的方法来为HTMLPurifier添加HTML5规则集?
HP可以通过以下方式configured to识别新标签:
// setup configurable HP instance
$config = HTMLPurifier_Config::createDefault();
$config->set('HTML.DefinitionID', 'html5 draft');
$config->set('HTML.DefinitionRev', 1);
$config->set('Cache.DefinitionImpl', null); // no caching
$def = $config->getHTMLDefinition(true);
// add a new tag
$form = $def->addElement(
'article', // name
'Block', // content set
'Flow', // allowed children
'Common', // attribute collection
array( // attributes
)
);
// add a new attribute
$def->addAttribute('a', 'contextmenu', "ID");
然而,这显然是一项工作。因为有很多新的HTML5标签和属性需要注册。新的全局属性应该可以与现有的HTML4标签组合。(很难从文档中判断如何扩充核心规则)。那么,是否有更有用的配置格式/数组结构来提供新的和更新的tag+attribute+context配置(内联/块/空/流/.)进入HTMLPurifier吗?
# mostly confused about how to extend existing tags:
$def->addAttribute('input', 'type', "...|...|...");
# or how to allow data-* attributes (if I actually wanted that):
$def->addAttribute("data-*", ...
当然,并不是所有新的HTML5标签都适合不受限制的许可。HTMLPurifier完全是关于内容过滤的。定义值约束就是它所在的位置。--例如,当<canvas>
出现在用户内容中时,它可能并不是什么大事。因为没有Javascript (惠普已经过滤掉了Javascript),它充其量也是没用的。但其他标签和属性可能并不理想;因此,灵活的配置结构对于启用/禁用标签及其相关属性是必不可少的。
(我想我应该更新一些研究...)。但是仍然没有适合HP配置的实用的概要/规范(不,XML不是)。
(呃,HTML5也不再是草稿了。)

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

HTMLpurify有一个允许更新的HTML5标签的配置。

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