Class HTMLPurifier_AttrDef

Base class for all validating attribute definitions.

This family of classes forms the core for not only HTML attribute validation, but also any sort of string that needs to be validated or cleaned (which means CSS properties and composite definitions are defined here too). Besides defining (through code) what precisely makes the string valid, subclasses are also responsible for cleaning the code if possible.

Methods summary
`abstract public`	# `validate( string $string, HTMLPurifier_Config $config, HTMLPurifier_Context $context )` Validates and cleans passed string according to a definition. Validates and cleans passed string according to a definition. Parameters `$string` `string` $string String to be validated and cleaned. `$config` `HTMLPurifier_Config` $config Mandatory HTMLPurifier_Config object. `$context` `HTMLPurifier_Context` $context Mandatory HTMLPurifier_Context object.
`public`	# `parseCDATA( mixed $string )` Convenience method that parses a string as if it were CDATA. 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.
`public HTMLPurifier_AttrDef`	# `make( string $string )` Factory method for creating this class from a string. Factory method for creating this class from a string. Parameters `$string` `string` $string String construction info Returns `HTMLPurifier_AttrDef` Created AttrDef object corresponding to $string
`protected string`	# `mungeRgb( string $string )` Removes spaces from rgb(0, 0, 0) so that shorthand CSS properties work properly. THIS IS A HACK! Removes spaces from rgb(0, 0, 0) so that shorthand CSS properties work properly. THIS IS A HACK! Parameters `$string` `string` $string a CSS colour definition Returns `string`
`protected`	# `expandCSSEscape( mixed $string )` Parses a possibly escaped CSS string and returns the "pure" version of it. Parses a possibly escaped CSS string and returns the "pure" version of it.
