Manipulate and transform HTML/XML documents and fragments
Description
Loofah is a general library for manipulating and transforming HTML/XML
documents and fragments, built on top of Nokogiri.
Loofah excels at HTML sanitization (XSS prevention). It includes some nice
HTML sanitizers, which are based on HTML5lib's safelist, so it most likely
won't make your codes less secure. (These statements have not been evaluated
