parseCDATA()

HTMLPurifier_AttrDef::parseCDATA ( $string )

inherited

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

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.

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()

HTMLPurifier_AttrDef_CSS::validate	(		$css,
			$config,
			$context )

Parameters

string	$css
HTMLPurifier_Config	$config
HTMLPurifier_Context	$context

Return values
