Overview

A filter for simplifying document structure by removing complex markups (mainly block elements) and complex contents.

The logic of this filter is similar to the ‘FinalSanitizer` filter, but this does not use the `sanitize` gem internally for the following reasons:

  • Each filter should do only its own responsibility, and this filter is not for sanitization.

  • The ‘sanitize` gem automatically adds extra transformers even if we want to clean up only some elements, and they would be run in the `FinalSanitizer` filter later. github.com/rgrove/sanitize/blob/v3.1.2/lib/sanitize.rb#L77-L100
