toNormalizedString() public method

This method normalizes a token into a string in a way that resembles DOM. The leading and trailing white space characters will be stripped. The entity and character references will be resolved Multiple whitespaces char will be collapsed into one. Whitespaces via entities will nonetheless be preserved. Creation date: (12/8/03 1:57:10 PM)
