Detailed Description

Parser that uses PHP 5's DOM extension (part of the core).

In PHP 5, the DOM XML extension was revamped into DOM and added to the core. It gives us a forgiving HTML parser, which we use to transform the HTML into a DOM, and then into the tokens. It is blazingly fast (for large documents, it performs twenty times faster than HTMLPurifier_Lexer_DirectLex,and is the default choice for PHP 5.

Note:: Any empty elements will have empty tokens associated with them, even if this is prohibited by the spec. This is cannot be fixed until the spec comes into play.; PHP's DOM extension does not actually parse any entities, we use our own function to do that.

Warning:: DOM tends to drop whitespace, which may wreak havoc on indenting. If this is a huge problem, due to the fact that HTML is hand edited and you are unable to get a parser cache that caches the the output of HTML Purifier while keeping the original HTML lying around, you may want to run Tidy on the resulting output or use HTMLPurifier_DirectLex

Reimplemented from HTMLPurifier_Lexer.

Member Function Documentation

callbackArmorCommentEntities ( $ matches )

Callback function that entity-izes ampersands in comments so that callbackUndoCommentSubst doesn't clobber them

Definition at line 216 of file DOMLex.php.

callbackUndoCommentSubst ( $ matches )

Callback function for undoing escaping of stray angled brackets in comments

Definition at line 208 of file DOMLex.php.

createEndNode	(	$	node,
		&$	tokens
	)		`[protected]`

Definition at line 176 of file DOMLex.php.

Here is the caller graph for this function:

createStartNode	(	$	node,
		&$	tokens,
		$	collect
	)		`[protected]`

Parameters:

$node	DOMNode to be tokenized.
$tokens	Array-list of already tokenized tokens.
$collect	Says whether or start and close are collected, set to false at first recursion because it's the implicit DIV tag you're dealing with.
