$minimized
$minimized
Tells us whether or not an HTML attribute is minimized.
Has no meaning in other contexts.
Validates the HTML type length (not to be confused with CSS's length).
This accepts integer pixels or percentages as lengths for certain HTML attributes.
parseCDATA(mixed $string) : mixed
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.
