HTMLPurifier_AttrDef_CSS_URI extends HTMLPurifier_AttrDef_URI
in package

Validates a URI in CSS syntax, which uses url('http://example.com')

Tags
note

While theoretically speaking a URI in a CSS document could be non-embedded, as of CSS2 there is no such usage so we're generalizing it. This may need to be changed in the future.

warning

Since HTMLPurifier_AttrDef_CSS blindly uses semicolons as the separator, you cannot put a literal semicolon in in the URI. Try percent encoding it, in that case.

Methods

__construct()

public __construct() : mixed

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.

expandCSSEscape()
