class Kramdown::Converter::RemoveHtmlTags

Removes all block (and optionally span) level HTML tags from the element tree.

This converter can be used on parsed HTML documents to get an element tree that will only contain native kramdown elements.

Note that the returned element tree may not be fully conformant (i.e. the content models of *some elements may be violated)!

This converter modifies the given tree in-place and returns it.
