Module: JekyllAutoThumbnails::HtmlParser

Defined in:
lib/jekyll-auto-thumbnails/html_parser.rb

Overview

Dispatch between Nokogiri’s HTML5 and libxml2-based HTML4 parsers.

HTML5 is the default throughout the gem; HTML4 is kept as an opt-in for users who depended on libxml2’s serialization quirks (notably the injected ‘<meta http-equiv=“Content-Type”>`).
