Constructor & Destructor Documentation

◆ __construct()

HTMLPurifier_Lexer_DOMLex::__construct ( )

Reimplemented from HTMLPurifier_Lexer.

Member Function Documentation

◆ callbackArmorCommentEntities()

HTMLPurifier_Lexer_DOMLex::callbackArmorCommentEntities ( $matches)

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

Parameters
array$matches
Return values
string

◆ callbackUndoCommentSubst()

HTMLPurifier_Lexer_DOMLex::callbackUndoCommentSubst ( $matches)

Callback function for undoing escaping of stray angled brackets in comments.

Parameters
array$matches
Return values
string

◆ CDATACallback()

static HTMLPurifier_Lexer::CDATACallback ( $matches)
staticprotectedinherited

Callback function for escapeCDATA() that does the work.

Warning
Though this is public in order to let the callback happen, calling it directly is not recommended.
Parameters
array$matchesPCRE matches array, with index 0 the entire match and 1 the inside of the CDATA section.
Return values
stringEscaped internals of the CDATA section.

◆ create()

static HTMLPurifier_Lexer::create ( $config)
staticinherited

Retrieves or sets the default Lexer as a Prototype Factory.

By default HTMLPurifier_Lexer_DOMLex will be returned. There are a few exceptions involving special features that only DirectLex implements.

Note
The behavior of this class has changed, rather than accepting a prototype object, it now accepts a configuration object. To specify your own prototype, set Core.LexerImpl to it. This change in behavior de-singletonizes the lexer object.
Parameters
HTMLPurifier_Config$config
Return values
HTMLPurifier_Lexer
Exceptions
HTMLPurifier_Exception

$collect,
$config )
protected
Parameters
DOMNode$nodeDOMNode to be tokenized.
HTMLPurifier_Token[]$tokensArray-list of already tokenized tokens.
bool$collectSays whether or start and close are collected, set to false at first recursion because it's the implicit DIV tag you're dealing with.
