Class Method Details

.parse(string_or_io, url = nil, encoding = nil, options = XML::ParseOptions::DEFAULT_HTML) {|options| ... }

Parse HTML. string_or_io may be a String, or any object that responds to read and close such as an IO, or StringIO. url is resource where this document is located. encoding is the encoding that should be used when processing the document. options is a number that sets options in the parser, such as XML::ParseOptions::RECOVER. See the constants in ::Nokogiri::XML::ParseOptions.

Yields:

#meta_encoding (rw)

Get the meta tag encoding for this document. If there is no meta tag, then nil is returned.

# File 'lib/nokogiri/html4/document.rb', line 12

  elsif (meta = meta_content_type)

  end
end

#meta_encoding=(encoding) (rw)

Set the meta tag encoding for this document.

If an meta encoding tag is already present, its content is replaced with the given text.

Otherwise, this method tries to create one at an appropriate place supplying head and/or html elements as necessary, which is inside a head element if any, and before any text node or content element (typically <body>) if any.

The result when trying to set an encoding that is different from the document encoding is undefined.

Beware in CRuby, that libxml2 automatically inserts a meta tag into a head element.

#title=(text) (rw)

Set the title string of this document.

If a title element is already present, its content is replaced with the given text.

Otherwise, this method tries to create one at an appropriate place supplying head and/or html elements as necessary, which is inside a head element if any, right after a meta encoding/charset tag if any, and before any text node or content element (typically <body>) if any.
