Class: HTMLPurifier_Lexer - X-Ref

Forgivingly lexes HTML (SGML-style) markup into tokens.

A lexer parses a string of SGML-style markup and converts them into
corresponding tokens.  It doesn't check for well-formedness, although its
internal mechanism may make this automatic (such as the case of
HTMLPurifier_Lexer_DOMLex).  There are several implementations to choose
from.

A lexer is HTML-oriented: it might work with XML, but it's not
recommended, as we adhere to a subset of the specification for optimization
reasons.

This class should not be directly instantiated, but you may use create() to
retrieve a default copy of the lexer.  Being a supertype, this class
does not actually define any implementation, but offers commonly used
convenience functions for subclasses.

create($config) X-Ref

Retrieves or sets the default Lexer as a Prototype Factory.

Depending on what PHP version you are running, the abstract base
Lexer class will determine which concrete Lexer is best for you:
HTMLPurifier_Lexer_DirectLex for PHP 4, and HTMLPurifier_Lexer_DOMLex
for PHP 5 and beyond. This general rule has a few exceptions to it
involving special features that only DirectLex implements.

param: $prototype Optional prototype lexer or configuration object
return: Concrete lexer.

HTMLPurifier_Lexer() X-Ref

No description

parseData($string) X-Ref

Parses special entities into the proper characters.

This string will translate escaped versions of the special characters
into the correct ones.

returns: Parsed character data.
param: $string String character data to be parsed.

tokenizeHTML($string, $config, &$context) X-Ref

Lexes an HTML string into tokens.

param: $string String HTML.
return: HTMLPurifier_Token array representation of HTML.

escapeCDATA($string) X-Ref

Translates CDATA sections into regular sections (through escaping).

returns: HTML with CDATA sections escaped.
param: $string HTML string to process.

escapeCommentedCDATA($string) X-Ref

Special CDATA case that is especiall convoluted for <script>

CDATACallback($matches) X-Ref

Callback function for escapeCDATA() that does the work.

returns: Escaped internals of the CDATA section.

normalize($html, $config, &$context) X-Ref

Takes a piece of HTML and normalizes it by converting entities, fixing
encoding, extracting bits, and other good stuff.

extractBody($html) X-Ref

Takes a string of HTML (fragment or document) and returns the content
