func Sanitize ¶ Uses

func Sanitize(w io.Writer, r io.Reader) (err error)

Sanitize strips all HTML nodes except allowed ones.

Unless explicitly specified, attributes are stripped. Allowed elements:

- p, br, hr
- h1, h2, h3, h4, h5, h6
- strong, em
- a
  - if href attribute is not a valid absolute HTTP(s) link, it is replaced
    with an innocuous one.
  - alt attribute is allowed
- ul, ol, li
- code, pre

Elements <script> and <style> are ignored entirely. For all other HTML nodes, Sanitize ignores the node, but visits its children.
