StripHTML

Overview

StripHTML(正式名称为 PlainHTML)是一个简单的扩展，在后期处理结束时运行。
它搜索最终输出，去掉不需要的注释和/或标记属性。 虽然它尽量在进程的最后加载，但在加载扩展时将它包含在最后会有所帮助。

<p>Here is a <strong>test</strong>.</p>

<!-- We are only allowing strip_comments and strip_js_on_attributes
     in this example. -->

Here is a <strong onclick="myFunction();">test</strong>.

Because comments aren't stripped until the end in a post-processing step, they are present throughout the entire Markdown conversion process and could possibly affect parsing, so be careful how you generally insert comments.

This is not meant to be a sanitizer for HTML. This is just meant to try and strip out style, script, classes, etc. to provide a plain HTML output for the times this is desired; this is not meant as a security extension. If you want something to secure the output, you should consider running a sanitizer like Bleach.

The StripHTML extension can be included in Python Markdown by using the following:

import markdown
md = markdown.Markdown(extensions=['pymdownx.striphtml'])

Options

By default, StripHTML strips the following attributes: style, id, class, and on<name>. StripHTML also strips HTML comments. If desired, its behavior can be configured to strip less or even more, but it is limited to attributes and comments.
