Member Function Documentation

◆ addNormalizedAttribute()

static Wikimedia\Parsoid\Utils\DOMDataUtils::addNormalizedAttribute	(	Element	$node,
		string	$name,
			$val,
			$origVal,
		bool	$skipOrig = false )

static

Set an attribute and shadow info to a node.

Similar to the method on tokens

Parameters

Element	$node	node
string	$name	Name of the attribute.
mixed	$val	value
mixed	$origVal	original value
bool	$skipOrig

◆ dumpRichAttribs()

static Wikimedia\Parsoid\Utils\DOMDataUtils::dumpRichAttribs	(	Element	$node,
		array &	$attrs,
		bool	$keepTmp,
		bool	$storeDiffMark )

static

Modify the attribute array, replacing data-object-id with JSON encoded data.

This is just a debugging hack, not to be confused with DOMDataUtils::storeDataAttribs(), and does not store flattened versions of attributes.

Parameters

Element	$node
array	&$attrs
bool	$keepTmp
bool	$storeDiffMark

◆ getAttributeDom()

static Wikimedia\Parsoid\Utils\DOMDataUtils::getAttributeDom	(	Element	$node,
		string	$name )

static

Return the value of a rich attribute as a live DocumentFragment.

This also serves as an assertion that there are not conflicting types.

Note: A string-valued attribute will be returned as a DocumentFragment with a single Text node. This supports the efficient serialization of 'simple' DocumentFragments as simple strings.

Parameters

Element	$node	The node on which the attribute is to be found.
string	$name	The name of the attribute.

Returns: ?DocumentFragment The attribute value, or null if not present.

◆ getAttributeDomDefault()

static Wikimedia\Parsoid\Utils\DOMDataUtils::getAttributeDomDefault	(	Element	$node,
		string	$name )

static

Return the value of a rich attribute as a DocumentFragment, creating a new document fragment and setting the attribute if the attribute was not previously present.

Parameters

Element	$node	The node on which the attribute is to be found.
string	$name	The name of the attribute.

Returns: DocumentFragment The attribute value.

◆ getAttributeObject()

static Wikimedia\Parsoid\Utils\DOMDataUtils::getAttributeObject	(	Element	$node,
		string	$name,
			$classHint )

static

Return the value of a rich attribute as a live (by-reference) object.

This also serves as an assertion that there are not conflicting types.

@template T

Parameters

Element	$node	The node on which the attribute is to be found.
string	$name	The name of the attribute.
	class-string<T>\|Hint<T>	$classHint

Returns: T|null The attribute value, or null if not present.

◆ getAttributeObjectDefault()

static Wikimedia\Parsoid\Utils\DOMDataUtils::getAttributeObjectDefault	(	Element	$node,
		string	$name,
			$classHint )

static

Return the value of a rich attribute as a live (by-reference) object.

This also serves as an assertion that there are not conflicting types. If the value is not present, a default value will be created using $codec->defaultValue() falling back to $className::defaultValue() and stored as the value of the attribute.

Note: The $className should have be JsonCodecable (either directly or via a custom JsonClassCodec).

@template T

Parameters

Element	$node	The node on which the attribute is to be found.
string	$name	The name of the attribute.
	class-string<T>\|Hint<T>	$classHint

Returns: T|null The attribute value, or null if not present.

These are intended be used on a document after post-processing, so that the underlying .dataobject is transparently applied (in the store case) and reloaded (in the load case), rather than worrying about keeping the attributes up-to-date throughout that phase.

For the most part, using this.ppTo* should be sufficient and using these directly should be avoided.

		string	$name,
		DocumentFragment	$value )

static

Set the value of a rich attribute, overwriting any previous value.

Generally mutating the result returned by the ::getAttribute*Default() methods should be done instead of using this method, since the objects returned are live.

string	$name	The name of the attribute.
DocumentFragment	$value

static

Set the value of a rich attribute, overwriting any previous value.

Generally mutating the result returned by the ::getAttribute*Default() methods should be done instead of using this method, since the objects returned are live.

Note: For attribute names where ::isHtmlAttributeWithSpecialSemantics() returns true you can customize the "flattened" representation used for HTML semantics via $codec->flatten() which falls back to $className::flatten().

Parameters

Element	$node	The node on which the attribute is to be found.

object	$value	The new (object) value for the attribute
class-string \| Hint \| null	$classHint	Optional serialization hint
