符合HTML5的HTMLfilter

有没有简单的方法来为HTMLPurifier添加HTML5规则集?

HP可以configuration为识别新标签:

// 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"); 

不过这显然是一些工作。 由于有很多新的HTML5标签和属性必须注册。 即使使用现有的HTML 4标签,新的全局属性也应该是可以组合的。 (从文档判断如何增加核心规则是很困难的)。 那么,是否有一个更有用的configuration格式/数组结构,以将新的更新的tag + attribute + contextconfiguration(inline / block / empty / flow / ..)提供给HTMLPurifier?

 # 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,并非所有新的HTML5标签都适合不受限制的补贴。 HTMLPurifier是关于内容过滤的。 定义价值约束是在哪里。 – 例如,当用户内容出现时, <canvas>可能不是那么重要。 因为在没有Javascript的情况下(惠普已经过滤掉),它是无用的。 但其他标签和属性可能是不可取的; 所以灵活的configuration结构对于启用/禁用标签及其相关属性是必不可less的。

猜猜我应该更新一些研究… )。 但是,仍然没有适合惠普configuration的实际纲要/规范(不,XML DTD不是)。

(呃,HTML5不再是草稿。)

PHP的tidy扩展可以configuration为识别html5标签。 http://tidy.sourceforge.net/docs/quickref.html#new-blocklevel-tags

HTMLpurify有这个configuration允许更新的HTML5标签。
