HTML_DOCTYPE_RE = :stopdoc: The following regexps are based on the ones used by REXML, with some slight modifications.

/<!DOCTYPE.*?>/m

HTML_COMMENT_RE =

/<!--(.*?)-->/m

HTML_INSTRUCTION_RE =

/<\?(.*?)\?>/m

HTML_ATTRIBUTE_RE =

/\s*(#{REXML::Parsers::BaseParser::UNAME_STR})(?:\s*=\s*(["'])(.*?)\2)?/m

HTML_TAG_RE =

/<((?>#{REXML::Parsers::BaseParser::UNAME_STR}))\s*((?>\s+#{REXML::Parsers::BaseParser::UNAME_STR}(?:\s*=\s*(["']).*?\3)?)*)\s*(\/)?>/m

HTML_TAG_CLOSE_RE =

/<\/(#{REXML::Parsers::BaseParser::UNAME_STR})\s*>/m

HTML_ENTITY_RE =

/&([\w:][\-\w\.:]*);|&#(\d+);|&\#x([0-9a-fA-F]+);/

HTML_CONTENT_MODEL_BLOCK =

%w{address applet article aside button blockquote body
             dd div dl fieldset figure figcaption footer form header hgroup iframe li map menu nav
noscript object section td}

HTML_CONTENT_MODEL_SPAN =

HTML_CONTENT_MODEL_RAW =

%w{script style math option textarea pre code}

HTML_CONTENT_MODEL = The following elements are also parsed as raw since they need child elements that cannot be expressed using kramdown syntax: colgroup table tbody thead tfoot tr ul ol

Hash.new {|h,k| h[k] = :raw}

HTML_SPAN_ELEMENTS = Some HTML elements like script belong to both categories (i.e. are valid in block and span HTML) and don’t appear therefore!

%w{a abbr acronym b big bdo br button cite code del dfn em i img input
ins kbd label option q rb rbc rp rt rtc ruby samp select small span
strong sub sup textarea tt var}

HTML_BLOCK_ELEMENTS =

%w{address article aside applet body button blockquote caption col colgroup dd div dl dt fieldset
figcaption footer form h1 h2 h3 h4 h5 h6 header hgroup hr html head iframe legend menu
li map nav ol optgroup p pre section summary table tbody td th thead tfoot tr ul}
