func Sanitize

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
• 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

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