Detailed Description

Helper class that provides missing DOM level 3 methods for the PHP DOM classes.

For a DOM method $node->foo( $bar) the equivalent helper is DOMCompat::foo( $node, $bar ). For a DOM property $node->foo there is a DOMCompat::getFoo( $node ) and DOMCompat::setFoo( $node, $value ).

Only implements the methods that are actually used by Parsoid.

Because this class may be used by code outside Parsoid it tries to be relatively tolerant of object types: you can call it either with PHP's DOM* types or with a "proper" DOM implementation, and it will attempt to Do The Right Thing regardless. As a result there are generally not parameter type hints for DOM object types, and the return types will be broad enough to accomodate the value a "real" DOM implementation would return, as well as the values our thunk will return. (For instance, we can't create a "real" NodeList in our compatibility thunk.)

Member Function Documentation

◆ getAttribute()

static Wikimedia\Parsoid\Utils\DOMCompat::getAttribute	(		$element,
		string	$attributeName )

static

Return the value of an element attribute.

Unlike PHP's version, this is spec-compliant and returns null if the attribute is not present, allowing the caller to distinguish between "the attribute exists but has the empty string as its value" and "the attribute does not exist".

Parameters

Element	$element
string	$attributeName

Returns: ?string The attribute value, or null if the attribute does not exist on the element.

See also: https://dom.spec.whatwg.org/#dom-element-getattribute

◆ getClassList()

static Wikimedia\Parsoid\Utils\DOMCompat::getClassList ( $node )

static

Return the class list of this element.

Parameters

Element $node

Returns: TokenList

See also: https://dom.spec.whatwg.org/#dom-element-classlist

◆ getElementById()

static Wikimedia\Parsoid\Utils\DOMCompat::getElementById	(		$node,
		string	$id )

static

Return the descendant with the specified ID.

Workaround for https://bugs.php.net/bug.php?id=77686 and other issues related to inconsistent indexing behavior. XXX: 77686 is fixed in php 8.1.21

Parameters

Document \| DocumentFragment	$node
string	$id

Returns: Element|null

See also: https://dom.spec.whatwg.org/#dom-nonelementparentnode-getelementbyid

◆ getElementsByTagName()

static Wikimedia\Parsoid\Utils\DOMCompat::getElementsByTagName	(		$node,
		string	$tagName )

static

Return all descendants with the specified tag name.

Workaround for PHP's getElementsByTagName being inexplicably slow in some situations and the lack of Element::getElementsByTagName().

Parameters

Document \| Element	$node
string	$tagName

Returns: (iterable<Element>&\Countable)|array<Element> Either an array or an HTMLCollection object

See also: https://dom.spec.whatwg.org/#dom-document-getelementsbytagname; https://dom.spec.whatwg.org/#dom-element-getelementsbytagname

Note: Note that unlike the spec this method is not guaranteed to return a NodeList (which cannot be freely constructed in PHP), just a traversable containing Elements.

◆ getInnerHTML()

static Wikimedia\Parsoid\Utils\DOMCompat::getInnerHTML ( $element )

static

Get innerHTML.

See also: DOMUtils::getFragmentInnerHTML() for the fragment version

Parameters

Element $element

Returns: string

See also: https://w3c.github.io/DOM-Parsing/#dom-innerhtml-innerhtml

◆ getLastElementChild()

static Wikimedia\Parsoid\Utils\DOMCompat::getLastElementChild ( $node )

static

Return the last child of the node that is an Element, or null otherwise.

Parameters

Document | DocumentFragment | Element $node

Returns: Element|null

See also: https://dom.spec.whatwg.org/#dom-parentnode-lastelementchild

◆ getNextElementSibling()

static Wikimedia\Parsoid\Utils\DOMCompat::getNextElementSibling ( $node )

static

Return the first following sibling of the node that is an element, or null otherwise.

Parameters

Node $node

Returns: Element|null

See also: https://dom.spec.whatwg.org/#dom-nondocumenttypechildnode-nextelementsibling

◆ getOuterHTML()

static Wikimedia\Parsoid\Utils\DOMCompat::getOuterHTML ( $element )

static

Get outerHTML.

Parameters

Element $element

Returns: string

See also: https://w3c.github.io/DOM-Parsing/#dom-element-outerhtml

◆ getPreviousElementSibling()

static Wikimedia\Parsoid\Utils\DOMCompat::getPreviousElementSibling ( $node )

static

Return the last preceding sibling of the node that is an element, or null otherwise.

Parameters

Node $node

Returns: Element|null

See also: https://dom.spec.whatwg.org/#dom-nondocumenttypechildnode-previouselementsibling

◆ getTitle()

static Wikimedia\Parsoid\Utils\DOMCompat::getTitle ( $document )

static

Get document title.

Parameters

Document $document

Returns: string

See also: https://html.spec.whatwg.org/multipage/dom.html#document.title

◆ newDocument()

static Wikimedia\Parsoid\Utils\DOMCompat::newDocument ( bool $isHtml )

static

Create a new empty document.

This is abstracted because the process is a little different depending on whether we're using Dodo or DOMDocument, and phan gets a little confused by this.

Parameters

bool $isHtml

Returns: Document

◆ nodeName()

static Wikimedia\Parsoid\Utils\DOMCompat::nodeName ( Node $node )

static

Return the lower-case version of the node name (HTML says this should be capitalized).

Parameters

Node $node

Returns: string

◆ normalize()

static Wikimedia\Parsoid\Utils\DOMCompat::normalize ( $elt )

static

Parameters

Element | DocumentFragment $elt root of the DOM tree that needs to be normalized

◆ querySelector()

static Wikimedia\Parsoid\Utils\DOMCompat::querySelector	(		$node,
		string	$selector )

static

Parameters

Document \| DocumentFragment \| Element	$node
string	$selector

Returns: Element|null

See also: https://dom.spec.whatwg.org/#dom-parentnode-queryselector

◆ querySelectorAll()

static Wikimedia\Parsoid\Utils\DOMCompat::querySelectorAll	(		$node,
		string	$selector )

static

Parameters

Document \| DocumentFragment \| Element	$node
string	$selector

Returns: (iterable<Element>&\Countable)|array<Element> Either a NodeList or an array

See also: https://dom.spec.whatwg.org/#dom-parentnode-queryselectorall

Note: Note that unlike the spec this method is not guaranteed to return a NodeList (which cannot be freely constructed in PHP), just a traversable containing Elements.

◆ remove()

static Wikimedia\Parsoid\Utils\DOMCompat::remove ( $node )

static

Removes the node from the document.

Parameters

Element | CharacterData $node

See also: https://dom.spec.whatwg.org/#dom-childnode-remove

◆ replaceChildren()

static Wikimedia\Parsoid\Utils\DOMCompat::replaceChildren	(		$parentNode,
			$nodes )

static

ParentNode.replaceChildren() https://developer.mozilla.org/en-US/docs/Web/API/ParentNode/replaceChildren.

Parameters

Document \| DocumentFragment \| Element	$parentNode
	string\|Node	...$nodes

◆ setIdAttribute()

static Wikimedia\Parsoid\Utils\DOMCompat::setIdAttribute	(		$element,
		string	$id )

static

Workaround bug in PHP's Document::getElementById() which doesn't actually index the 'id' attribute unless you use the non-standard Element::setIdAttribute method after the attribute is set; see https://www.php.net/manual/en/domdocument.getelementbyid.php for more details.

Parameters

Element	$element
string	$id	The desired value for the `id` attribute on $element.

See also: https://phabricator.wikimedia.org/T232390

		string	$html )
