2d9b5cb098 HTML API: Add class name utilities has_class() and class_list().
This patch adds two new public methods to the HTML Tag Processor:
 - `has_class()` indicates if a matched tag contains a given CSS class name.
 - `class_list()` returns a generator to iterate over all the class names in a matched tag.

Included in this patch is a refactoring of the internal logic when matching
a tag to reuse the new `has_class()` function. Previously it was relying on
optimized code in the `matches()` function which performed byte-for-byte
class name comparison. With the change in this patch it will perform class
name matching on the decoded value, which might differ if a class attribute
contains character references.

These methods may be useful for running more complicated queries based
on the presence or absence of CSS class names. The use of these methods
avoids the need to manually decode the class attribute as reported by
`$process->get_attribute( 'class' )`.

374bcd9b3d HTML API: Add matches_breadcrumbs() method for better querying.
Inside a `next_tag()` loop it can be challenging to use breadcrumbs because they are only exposed inside the call to `next_tag()` via the `$query` arg.

In this patch a new method, `matches_breadcrumbs()`, is exposed which allows for querying within the `next_tag()` loop for more complicated queries.

This method exposes a wildcard `*` operator to allow matching ''any HTML tag'' that the currently-matched tag is a child or descendant of.

061c32d574 HTML API: Remove all duplicate copies of an attribute when removing.
When encountering an HTML tag with duplicate copies of an attribute the tag processor ignores the duplicate values, according to the specification. However, when removing an attribute it must remove all copies of that attribute lest one of the duplicates becomes the primary and it appears as if no attributes were removed.

In this patch we're adding tests that will be used to ensure that all attribute copies are removed from a tag when one is request to be removed.

**Before**

{{{#!php
<?php
$p = new WP_HTML_Tag_Processor( '<br id=one id="two" id='three' id>' );
$p->next_tag();
$p->remove_attribute( 'id' );
$p->get_updated_html();
// <br id="two" id='three' id>
}}}

**After**

{{{#!php
<?php
$p = new WP_HTML_Tag_Processor( '<br id=one id="two" id='three' id>' );
$p->next_tag();
$p->remove_attribute( 'id' );
$p->get_updated_html();
// <br>
}}}

Previously we have been overlooking duplicate attributes since they don't have an impact on what parses into the DOM. However, as one unit test affirmed (asserting the presence of the bug in the tag processor) when removing an attribute where duplicates exist this meant we ended up changing the value of an attribute instead of removing it.

In this patch we're tracking the text spans of the parsed duplicate attributes so that ''if'' we attempt to remove them then we'll have the appropriate information necessary to do so. When an attribute isn't removed we'll simply forget about the tracked duplicates. This involves some overhead for normal operation ''when'' in fact there are duplicate attributes on a tag, but that overhead is minimal in the form of integer pairs of indices for each duplicated attribute.

deaa431a90 HTML API: Skip over contents of RAWTEXT elements such as STYLE.
When encountering elements that imply switching into the RAWTEXT parsing state,
the Tag Processor should skip processing until exiting the RAWTEXT state.

In this patch the Tag Processor does just that, except for the case of the
deprecated XMP element which implies further and more complicated rules.

There's an implicit assumption that the SCRIPT ENABLED flag in HTML parsing
is enabled so that the contents of NOSCRIPT can be skipped. Otherwise, it would
be required to parse the contents of that tag.

b80ce60f70 Coding Standards: Use pre-increment/decrement for stand-alone statements.
Note: This is enforced by WPCS 3.0.0:

1. There should be no space between an increment/decrement operator and the variable it applies to.
2. Pre-increment/decrement should be favoured over post-increment/decrement for stand-alone statements. “Pre” will in/decrement and then return, “post” will return and then in/decrement. Using the “pre” version is slightly more performant and can prevent future bugs when code gets moved around.

c67fe4b6e5 HTML API: Stop processing HTML when encountering unsupported markup.
It was a design goal of the HTML Processor to abort processing its input document when encountering unsupported markup. Unfortunately there was no test for this and so-far, the HTML Processor has paused, but continued processing in these situations.

In this patch a new test ensures that the HTML Processor stops and refuses to move forward after encountering any unsupported markup. It also ensures that it doesn't report any current tag names since unsupported markup could imply that the read tag name is different than the parsed tag name.

12884f0361 HTML API: Add support for BUTTON element.
This patch adds support to process the BUTTON element. This requires adding some additional semantic rules to handle situations where a BUTTON element is already in scope.

Also included is a fixup to enforce that `WP_HTML_Processor::next_tag()` never returns for a tag closer. This is useful with the Tag Processor, but not for the HTML Processor. There were tests relying on this behavior to assert that internal processes were working as they should, but those tests have been updated to use the semi-private `step()` function, which does stop on tag closers.

This patch is one in a series of changes to expand support within the HTML API, moving gradually to allow for more focused changes that are easier to review and test. The HTML Processor is a work in progress with a certain set of features slated to be ready and tested by 6.4.0, but it will only contain partial support of the HTML5 specification even after that. Whenever it cannot positively recognize and process its input it bails, and certain function stubs and logical stubs exist to structure future expansions of support.

fa83c8e1cd HTML API: Adjust code styling to Gutenberg's linter's preferences.
Adjust the code style according to the rules that the linting process in Gutenberg requires.

There are only a couple code changes that should have no effect on the runtime:
 - A missing check to verify that only `UTF-8` is supported has been added (brought up because it was identified as an undefined variable).
 - A few `return false;` statements have been added to avoid having the linter complain that functions don't return a value despite indicating they return `bool`. The functions are stubs for coming support and currently `throw`, so the `return` statements are unreachable.

8fa9aad5e6 HTML API: Add support for SPAN element.
In this patch we're introducing support for the SPAN element, which is the first
in the class of "any other tag" in the "in body" insertion mode.

This patch introduces the mechanisms required to handle that class of tags but
only introduces SPAN to keep the change focused. With the tests and mechanisms
in place it will be possible to follow-up and add another limited set of tags.

It's important that this not use the default catch-all in the switch handling
`step_in_body` because that would catch tags that have specific rules in previous
case statements that aren't yet added. For example, we don't want to treat the
`TABLE` element as "any other tag".

44629e6286 HTML-API: Introduce minimal HTML Processor.
This patch introduces the //first// of //many// iterations on the evolution of the HTML API, the HTML Processor, which is built in order to understand HTML structure including nesting, misnesting, and complicated semantic rules.

In the first iteration, the HTML Processor is arbitrarily limited to a minimal subset of functionality so that we can review it, ship it, test it, and collect feedback before moving forward. This means that this patch is more or less an extension to the Tag Processor query language, providing the ability not only to scan for a tag of a given name, but also to find an HTML element in a specific nesting path.

The HTML Processor also aborts any time it encounters:
 - a tag that isn't a `P`, `DIV`, `FIGURE`, `FIGCAPTION`, `IMG`, `STRONG`, `B`, `EM`, `I`, `A`, `BIG`, `CODE`, `FONT`, `SMALL`, `STRIKE`, `TT`, or `U` tag. this limit exists because many HTML elements require specific rules and we are trying to limit the number of rules introduced at once. this work is targeted at existing work in places like the image block.
 - certain misnesting constructs that evoke complicated resolution inside the HTML spec. where possible and where simple to do reliably, certain parse errors are handled. in most cases the HTML Processor aborts.

The structure of the HTML Processor is established in this patch. Further spec-compliance comes through filling out //more of the same// kind and nature of code as is found in this patch. Certain critical HTML algorithms are partially supported, and where support requires more than is present, the HTML Processor acknowledges this and refuses to operate.

In this patch are explorations for how to verify that new HTML support is fully added (instead of allowing for partial updates that leave some code paths non-compliant). Performance is hard to measure since support is so limited at the current time, but it should generally follow the performance of the Tag Processor somewhat close as the overhead is minimized as much as practical.

5a32396d8f HTML API: Accumulate shift for internal parsing pointer.
A bug was discovered where where the parser wasn't returning to the
start of the affected tag after making some updates.

In few words, the Tag Processor has not been treating its own internal
pointer `bytes_already_parsed` the same way it treats its bookmarks.
That is, when updates are applied to the input document and then
`get_updated_html()` is called, the internal pointer transfers to
the newly-updated content as if no updates had been applied since
the previous call to `get_updated_html()`.

In this patch we're creating a new "shift accumulator" to account for
all of the updates that accrue before calling `get_updated_html()`.
This accumulated shift will be applied when swapping the input document
with the output buffer, which should result in the pointer pointing to
the same logical spot in the document it did before the udpate.

In effect this patch adds a single workaround for treating the
internal pointer like a bookmark, plus a temporary pointer which points
to the beginning of the current tag when calling `get_updated_html()`.
This will preserve the assumption that updating a document doesn't
move that pointer, or shift which tag is currently matched.

3b58785908 HTML API: Ensure attribute updates happen only once for case variants.
When setting a new value for an attribute multiple times and providing
multiple case variations of the attribute name the Tag Processor has
been appending multiple copies of the attribute into the updated HTML.

This means that only the first attribute set determines the value in
the final output, plus the output will //appear// wrong.

In this patch we're adding a test to catch the situation and resolving it
by using the appropriate comparable attribute name as a key for storing
the updates as we go. Previously we stored updates to the attribute by
its given `$name`, but when a new update of the same name with a
case variant was queued, it would not override the previously-enqueued
value as it out to have.

While `WP_HTML_Tag_Processor` currently only supports changing a given tag's attributes, the plan is to provide methods to make broader changes (possibly through a subclass of `WP_HTML_Tag_Processor`). The API will have the potential of replacing a tag that a bookmark points to. To prepare, this changeset makes sure that all bookmarks affected by a HTML replacement are invalidated (i.e. released).

Changes:
* Extends the existing loop in `WP_HTML_Tag_Processor::apply_attributes_updates()` that adjusts bookmarks' start and end positions upon HTML changes to check if the entire bookmark is within a portion of the HTML that has been replaced.
* Adds `WP_HTML_Tag_Processor::has_bookmark() to check whether the given bookmark name exists.

1579f32cc6 HTML API: Fix finding bookmarks set on closing tag WP_HTML_Tag_Processor.
Setting a bookmark on a tag should set its "start" position before the opening "<", e.g.:
{{{
<div> Testing a <b>Bookmark</b>
----------------^
}}}

The previous calculation assumed this is always one byte to the left from `$tag_name_starts_at`.

However, in a closing tag that index points to a solidus symbol "/":
{{{
<div> Testing a <b>Bookmark</b>
----------------------------^
}}}

The bookmark should therefore start two bytes before the tag name:
{{{
<div> Testing a <b>Bookmark</b>
---------------------------^
}}}

This changeset achieves this by:
* Using the correct starting index for closing tag bookmarks.
* Adding `array( 'tag_closers' => 'visit' )` in `WP_HTML_Tag_Processor::seek()`.

582feb3ffb HTML API: Set $this->html to protected to support subclassing
When the HTML API was introduced a number of fields were switched from private visibility to protected so that Gutenberg and other systems could more easily enhance the behaviors through subclassing. The $this->html property was overlooked but important for systems using the Tag Processor to stich HTML, specifically performing operations on innerHTML and innerText.

09cc873d3a Docs: Replace short array syntax in WP_HTML_Tag_Processor documentation.
Per [https://developer.wordpress.org/coding-standards/wordpress-coding-standards/php/#declaring-arrays WordPress PHP Coding Standards]:
> Using long array syntax ( `array( 1, 2, 3 )` ) for declaring arrays is generally more readable than short array syntax ( `[ 1, 2, 3 ]` ), particularly for those with vision difficulties. Additionally, it’s much more descriptive for beginners.
> 
> Arrays must be declared using long array syntax.

be73904dc7 Introduce HTML API with HTML Tag Processor
This commit pulls in the HTML Tag Processor from the Gutenbeg repository.

The Tag Processor attempts to be an HTML5-spec-compliant parser that provides the ability in PHP to find specific HTML tags and then add, remove, or update attributes on that tag. It provides a safe and reliable way to modify the attribute on HTML tags.
