NAME

       CSS::DOM::Exception - The Exception interface for CSS::DOM

SYNOPSIS

	 use CSS::DOM::Exception 'SYNTAX_ERR';

	 eval {
		 die new CSS::DOM::Exception
			 SYNTAX_ERR,
			 '1 is not a valid property declaration'
	 };

	 $@ == SYNTAX_ERR; # true

	 print $@;    # prints "1 is not a valid property declaration
";

DESCRIPTION

       This module implementations the W3C's DOMException interface.  CSS::DOM::Exception objects stringify to the message passed to the
       constructer and numify to the error number (see below, under 'EXPORTS').

METHODS

       new CSS::DOM::Exception $type, $message
	   This class method creates a new exception object. $type is expected to be an integer (you can use the constants listed under
	   'EXPORTS').	$message is the error message.

EXPORTS

       The following constants are optionally exported. The descriptions are copied from the DOM spec.

       INDEX_SIZE_ERR(1)
	   If index or size is negative, or greater than the allowed value

       DOMSTRING_SIZE_ERR(2)

       INVALID_CHARACTER_ERR(5)
	   If an invalid character is specified, such as in a name.

       NO_DATA_ALLOWED_ERR(6)
	   If data is specified for a node which does not support data

       NO_MODIFICATION_ALLOWED_ERR(7)
	   If an attempt is made to modify an object where modifications are not allowed

       NOT_FOUND_ERR(8)
	   If an attempt was made to reference a node in a context where it does not exist

       NOT_SUPPORTED_ERR(9)
	   If the implementation does not support the type of object requested

       INUSE_ATTRIBUTE_ERR(10)
	   If an attempt is made to add an attribute that is already inuse elsewhere

NAME

       CSS::DOM::Util - Utility functions for dealing with CSS tokens

VERSION

       Version 0.14

SYNOPSIS

	 use CSS::DOM::Util ':all';
	 # or:
	 use CSS::DOM::Util qw[
	   escape unescape
	   escape_ident unescape_url
	   escape_str unescape_str
	 ];

DESCRIPTION

       This module provides utility functions for dealing with CSS tokens.

FUNCTIONS

       All functions below that take one argument have a "($)" prototype, so they have the same precedence as "closedir" and "delete".

       escape $string, $chars_to_escape
	   This escapes any characters in $string that occur in $chars_to_escape, which is interpreted as a regular expression. The regexp must
	   consume just one character; otherwise you'll find chars missing from the output. ASCII vertical whitespace (except the vertical tab) is
	   always escaped.

	   Printable non-alphanumeric ASCII characters and the space character are escaped with a single backslash. Other characters are encoded
	   in hexadecimal.

	   "escape" also considers that you might want to include the escaped string in a larger string, so it appends a space if the escaped
	   string ends with a hexadecimal escape with fewer than six digits.

       unescape $string
	   This turns something like "H65llo" into "Hello" (including quotes).

       escape_ident $string
       escape_ident $string, $more_chars_to_escape
	   This escapes $string as a CSS identifier, escaping also any characters matched by $more_chars_to_escape.

       unescape_url $url_token
	   Returns the URL that the token represents.

       escape_str $string
	   Returns a CSS string token containing $string (within quotes; characters possibly escaped).

       unescape_str $string_token
	   Returns the value that a CSS string token represents.
