parseCDATA()

Convenience method that parses a string as if it were CDATA.

public parseCDATA(mixed $string) : mixed

This method process a string in the manner specified at http://www.w3.org/TR/html4/types.html#h-6.2 by removing leading and trailing whitespace, ignoring line feeds, and replacing carriage returns and tabs with spaces. While most useful for HTML attributes specified as CDATA, it can also be applied to most CSS values.

Parameters
$string : mixed
Tags
note

This method is not entirely standards compliant, as trim() removes more types of whitespace than specified in the spec. In practice, this is rarely a problem, as those extra characters usually have already been removed by HTMLPurifier_Encoder.

warning

This processing is inconsistent with XML's whitespace handling as specified by section 3.3.3 and referenced XHTML 1.0 section 4.7. However, note that we are NOT necessarily parsing XML, thus, this behavior may still be correct. We assume that newlines have been normalized.

validate()

Validates and cleans passed string according to a definition.

public validate(string $number, HTMLPurifier_Config $config, HTMLPurifier_Context $context) : string|bool
Parameters
$number : string
$config : HTMLPurifier_Config
$context : HTMLPurifier_Context
Tags
warning

Some contexts do not pass $config, $context. These variables should not be used without checking HTMLPurifier_Length

Return values
string|bool
