Unreleased

Added

Removed

  • Remove support for Elixir 1.13 and OTP 22.

0.36.3 - 2024-10-21

This release contains some performance improvements, thanks to @ypconstante.

Fixed

  • Stop Floki.get_by_id/2 traversal on first match. Thanks @ypconstante.

  • Remove extra whitespaces from nodes without attributes on Floki.raw_html/1. Thank you @ypconstante.

  • Fix Floki.raw_html/1 typespecs. Thanks @davydog187.

0.36.2 - 2024-04-26

Added

  • Implement the Inspect protocol for the Floki.HTMLTree struct. This struct is currently private. Thank you @vittoriabitton.

Fixed

  • Fix regression to respect config option :encode in Floki.raw_html/2. Thanks @Sgoettschkes.

  • Make the Floki.raw_html/2 treat the contents of the <title> tag as plain text. The idea is to align with parse_document/2. Thank you @aymanosman.

0.36.1 - 2024-03-18

Fixed

  • Fix typespec of get_by_id/2.

0.36.0 - 2024-03-01

Added

  • Add Floki.get_by_id/1 that returns one element by ID or nil. Thanks @SteffenDE.

Changed

  • Improve options validation with Keyword.validate!/2. This is not a change in APIs, but the error messages and opts validation should be standardized now. Thanks @vittoriabitton.

Removed

  • Drop support for Elixir v1.12.

0.35.4 - 2024-02-19

Besides the fix described below, this release also contains more performance improvements, thanks to @ypconstante.

Fixed

  • Fix order of results for Floki.find/2. This was a regression from the previous version - thanks @ypconstante.

0.35.3 - 2024-01-25

This release has great performance improvements, thanks to the PRs from @ypconstante!

Most of the main functions, such as Floki.raw_html/2 and Floki.find/2 are faster and are using less memory. It's something like twice as fast, and half usage of memory for find/2, for example.

Fixed

  • Add :leex to Mix compilers. Fixes the build when running with dev version of Elixir. Thanks @wojtekmach.

  • Fix Floki.raw_html/2 when a tree using attributes as maps is given. Thanks @SupaMic.

  • Add a guard to Floki.find/2 so people can have a better error message when an invalid input is given. Thanks @Hajto.

  • Fix parsers to consider IO data as inputs. This may change in the next version of Floki, as I plan to drop support for IO data. Thanks @ypconstante.

Removed

  • Remove outdated Gleam wrapper code. The external functions syntax in Gleam has changed. So now the wrapper is not needed anymore. Thanks @michallepicki.

0.35.2 - 2023-10-25

Fixed

  • Enable usage of IO data by removing a guard for binaries in the main parser module.

0.35.1 - 2023-10-16

Fixed

  • Fix a small regression of the mochiweb parser that was breaking when a malformed HTML was used. For more details, see the original issue: #492

0.35.0 - 2023-10-13

Added

  • Add support for parsing attributes as maps.

    This makes parse_document/2 and parse_fragment/2 accept the option :attributes_as_maps to change the behaviour and return attributes as maps instead of lists of tuples. The only parser that does not support it yet is the fast_html.

Changed

  • Drop support for Elixir v1.11.

  • Change the log level of parsing logger calls from "info" to "debug". This will help to reduce the amount of noise in production apps.

0.34.3 - 2023-06-02

Added

  • Add boolean option :include_inputs to Floki.text/2 that changes the result of this function to include the values of inputs. So if there is any input with a "value" attribute, we now include that value if this option is set to true. Thanks @viniciusmuller.

Fixed

  • Fix find of elements by classes that contain colons. This is useful for when people are trying to find elements that contain Tailwind classes. Thanks @viniciusmuller.

  • Fix some typespecs that were using types from private modules. This is a fix to the documentation.

0.34.2 - 2023-02-24

Added

  • Add option to pass down arguments to the parser in Floki.parse_document/2 and Floki.parse_fragment/2. Thanks @Kuret.

  • Add support for returning more elements from the Floki.traverse_and_update/2 function callback. This enables the creation of more elements in the tree, but should be used with care, since the tree can grow a lot if the change is not controlled. Thanks @martosaur.

0.34.1 - 2023-02-11

Fixed

  • Fix pseudo-class ":not" selector parsing halting point. This is a fix for when a "pseudo-class" ":not" that contains an attribute selector is followed by another selector. This is an example: "a:not([class]), div".

  • Ignore decimal numeric char ref when number is negative.

0.34.0 - 2022-11-03

Added

  • User configurable "self-closing" tags. Now it's possible to define which tags are considered "self-closing". Thanks @inoas.

Fixed

  • Allow attribute values to not be escaped. This fixes Floki.raw_html/2 when used with the option encode: false. Thanks @juanazam.
  • Fix traverse_and_update/3 spec. Thanks @WLSF.

Changed

  • Drop support for Elixir 1.9 and 1.10.
  • Remove html_entities dependency. We now use an internal encoder/decoder for entities.
  • Change the main branch name to main.

0.33.1 - 2022-06-28

Fixed

  • Remove some warnings for unused code.

0.33.0 - 2022-06-28

Added

  • Add support for searching elements that contains text in a case-insensitive manner with fl-icontains - thanks @nuno84

Changed

  • Drop support for Elixir 1.8 and 1.9.
  • Fix and improve internal things - thanks @derek-zhou and @hissssst

0.32.1 - 2022-03-24

Fixed

  • Allow root nodes to be selected using pseudo-classes - thanks @rzane

0.32.0 - 2021-10-18

Added

  • Add an HTML tokenizer written in Elixir - this still experimental and it's not stable API yet.
  • Add support for HTML IDs containing periods in the selectors - thanks @Hugo-Hache
  • Add support for case-insensitive CSS attribute selectors - thanks @fcapovilla
  • Add the :root pseudo-class selector - thanks @fcapovilla

0.31.0 - 2021-06-11

Changed

  • Treat style and title tags as plaintext in Mochiweb - thanks @SweetMNM

0.30.1 - 2021-03-29

Fixed

  • Fix typespecs of Floki.traverse_and_update/2 to make clear that it does not accept text nodes directly.

0.30.0 - 2021-02-06

Added

  • Add ":disabled" pseudo selector - thanks @vnegrisolo
  • Add Gleam adapter - thanks @CrowdHailer
  • Add pretty option to Floki.raw_html/2 - thanks @evaldobratti

  • Replace IO.warn by Logger.info for deprecation warnings - thanks @juulSme

Fixed

  • Fix typespecs for find, attr and attribute functions - thanks @mtarnovan
  • Documentation Improvements - thanks @kianmeng

0.29.0 - 2020-10-02

Added

  • Add Floki.find_and_update/3 that updates nodes inside a tree, like traverse and update but without allowing changes in the children nodes. There for the tree cannot grow in size, but can have nodes removed.

Changed

  • Deprecate Floki.map/2 because we have now Floki.find_and_update/3 and Floki.traverse_and_update/2 that are powerful APIs. Floki.map/2 can be replaced by Enum.map/2 as well - thanks @josevalim for the idea!
  • Update optional dependency fast_html to v2.0.4

Fixed

  • Fix the typespecs of Floki.traverse_and_update/3 - thanks @RichMorin

Changed

  • Update optional dependency fast_html to v1.0.3

0.25.0 - 2020-01-26

Added

  • Add Floki.parse_fragment!/1 and Floki.parse_document!/1 that has the same functionality of the functions without the bang, but they return the document or fragment without the either tuple and will raise exception in case of errors - thanks @schneiderderek
  • Add Floki.traverse_and_update/3 which accepts an accumulator which is useful to keep the state while traversing the HTML tree - thanks @Dalgona

Changed

  • Update the html_entities dependency from v0.5.0 to v0.5.1

0.24.0 - 2020-01-01

  • Add setup to run our test suite against all parsers on CI - thanks @rinpatch
  • Add Floki.parse_document/1 and Floki.parse_fragment/1 in order to correct parse documents and fragments of documents - it also prevents the confusion and inconsistency of parse/1.
  • Configure dialyxir in order to run Dialyzer easily.

Changed

  • Deprecate Floki.parse/1 and all the functions that uses it underneath. This means that all the functions that accepted HTML as binary are deprecated as well. This includes find/2, attr/4, filter_out/2, text/2 and attribute/2. The recommendation is to use those functions with an already parsed document or fragment.
  • Remove support for Elixir 1.5.

Fixed

  • It fixes the Mochiweb parser when there is an invalid charref.

0.4.0 - 2015-09-17

Added

  • A robust representation of selectors in order to enable queries using a mix of selector types, such as classes with attributes, attributes with types, classes with classes and so on. Here is a list with examples of what is possible now:
    • Floki.find(html, "a.foo")
    • Floki.find(html, "a.foo[data-action=post]")
    • Floki.find(html, ".foo.bar")
    • Floki.find(html, "a.foo[href$='.org']") Thanks to @licyeus to point out the issue!
  • Include mochiweb in the applications list at mix.exs - thanks @EricDykstra

0.2.1 - 2015-06-04

Fixed

  • Fix parse/1 when parsing a part of HTML without a root node - @antonmi

0.2.0 - 2015-05-03
