[Unreleased]

Added

Changed

Deprecated

Removed

Fixed

Security

[2.0.5] - 2021-03-19

Fixed

  • Support Mageia distros when libxml2/libxslt system libraries are install. #165 (Thank you, @pterjan!)

Added

  • Forward-looking support for a version of Nokogiri that will provide HTML5 parsing. #171

Improved

  • Update extconf.rb to use Nokogiri v1.11's CPPFLAGS for more reliable installation. #163

[2.0.4] - 2020-11-27

Fixed

  • Fixed a bug where Nokogiri::HTML5.fragment(nil) would raise an error. Now it returns an empty DocumentFragment like it did in v2.0.2.
  • Fixed assertion failure when a tag immediately followed the UTF-8 BOM.

[2.0.3] - 2020-11-21

Added

  • Limit enforced on number of attributes per element, defaulting to 400 and configurable with the :max_attributes argument.

Fixed

  • Ignore UTF-8 byte order mark at the beginning of the input.
  • Fix content sniffing for Unicode strings.
  • Fixed crash where Ruby objects constructed in C can be garbage collected.

[2.0.2] - 2019-11-19

Added

  • Support Ruby 2.6

Fixed

  • Fix assertion failures with nonstandard HTML tags.
  • Fix the handling of mis-nested formatting tags (the adoption agency algorithm).
  • Fix crash with zero-length HTML tags.

Security

  • Prevent 1-byte buffer over read when constructing an error message about an unexpected EOF.

[2.0.1] - 2018-11-11

Fixed

  • Fix line numbers on elements from #line.

[2.0.0] - 2018-10-04

Added

  • Experimental support for errors (it was supported in 1.5.0 but undocumented).
  • Added proper HTML5 serialization.
  • Added option :max_errors to control the maximum number of errors reported by #errors.
  • Added option :max_tree_depth to control the maximum parse tree depth.
  • Line number support via Nokogiri::XML::Node#line as long as Nokogumbo has been compiled with libxml2 support.

Changed

  • Integrated Gumbo parser into Nokogumbo. A system version will not be used.
  • The undocumented (but publicly mentioned) :max_parse_errors renamed to :max_errors; :max_parse_errors is deprecated and will go away
  • The various #parse and #fragment (and Nokogiri.HTML5) methods return Nokogiri::HTML5::Document and Nokogiri::HTML5::DocumentFragment classes rather than Nokogiri::HTML::Document and Nokogiri::HTML::DocumentFragment.
  • Changed the top-level API to more closely match Nokogiri's while maintaining backwards compatibility. The new APIs are
    • Nokogiri::HTML5(html, url = nil, encoding = nil, **options, &block)
    • Nokogiri::HTML5.parse(html, url = nil, encoding = nil, **options, &block)
    • Nokogiri::HTML5::Document.parse(html, url = nil, encoding = nil, **options, &block)
    • Nokogiri::HTML5.fragment(html, encoding = nil, **options)
    • Nokogiri::HTML5::DocumentFragment.parse(html, encoding = nil, **options)
    • Nokogiri::HTML5::DocumentFragment.new(document, html = nil, ctx = nil)
    • Nokogiri::HTML5::Document#fragment(html = nil)
    • Nokogiri::XML::Node#fragment(html = nil) In all cases, html can be a string or an IO object (something that responds to #read). The url parameter is entirely for error reporting, as in Nokogiri. The encoding parameter only signals what encoding html should have on input; the output Document or DocumentFragment will be in UTF-8. Currently, the only options supported are :max_errors which controls the maximum number of reported by #errors.
  • Minimum supported version of Ruby changed to 2.1.
  • Minimum supported version of Nokogiri changed to 1.8.0.
  • Nokogiri::HTML5::DocumentFragment#errors returns errors for the document fragment itself, not the underlying document.
  • The five XML namespaces described in the HTML spec, MathML, SVG, XLink, XML, and XMLNS, are now supported. Thus <svg> will create an svg element in the SVG namespace and <math> will create a math element in the MathML namespace. An attribute xml:lang=en, for example, will create a lang attribute in the XML namespace, but only in foreign elements (i.e., those in the SVG or MathML namespaces). On HTML elements, this creates an attribute with the name xml:lang. This changes the #xpath and related APIs.
  • Calling #to_xml on a Nokogiri::HTML5::Document will produce XML output rather than HTML.

Deprecated

  • :max_parse_errors; use :max_errors

Fixed

  • Fixed documents failing to serialize (via to_html) if they contain certain meta elements that set the charset.
  • Documents are now properly marked as UTF-8 after parsing.
  • Fixed Nokogiri::HTML5.fragment reporting an error due to a missing <!DOCTYPE html>.
  • Fixed crash when input contains U+0000 NULL bytes and error reporting is enabled.

Security

  • The most recent, released version of Gumbo has a potential security issue that could result in a cross-site scripting vulnerability. This has been fixed by integrating Gumbo into Nokogumbo.
