Detailed Description

Differences from DOM schema:

• attribute nodes are children
• "<h>" nodes that aren't at the top are replaced with <possible-h>

Nodes are stored in a recursive array data structure. A node store is an array where each element may be either a scalar (representing a text node) or a "descriptor", which is a two-element array where the first element is the node name and the second element is the node store for the children.

Attributes are represented as children that have a node name starting with "@", and a single text node child.

Todo:

: Consider replacing descriptor arrays with objects of a new class. Benchmark and measure resulting memory impact.

Parameters

array

$values

Returns

PPNode_Hash_Array

Reimplemented from Preprocessor.

Definition at line 73 of file Preprocessor_Hash.php.

preprocessToObj()

Preprocessor_Hash::preprocessToObj	(		$text,
			$flags = 0
	)

Preprocess some wikitext and return the document tree.

Parameters

string	$text	The text to parse
int	$flags	Bitwise combination of: Parser::PTD_FOR_INCLUSION Handle "<noinclude>" and "<includeonly>" as if the text is being included. Default is to assume a direct page view.

The generated DOM tree must depend only on the input text and the flags. The DOM tree must be the same in OT_HTML and OT_WIKI mode, to avoid a regression of T6899.

Any flag added to the $flags parameter here, or any other parameter liable to cause a change in the DOM tree for a given text, must be passed through the section identifier in the section edit link and thus back to extractSections().

Exceptions

MWException

Returns

PPNode_Hash_Tree
