Operations That Evaluate HTML and XML Encoding

HTML or XML Operation	Description
text.SET_TEXT_	Specifies whether or not backslash decoding is
MODE(BACKSLASH_ENCODEDNO_	performed on the text object represented by text.
BACKSLASH_ENCODED)	If BACKSLASH_ENCODED is specified, the SET_
	TEXT_MODE operator performs the following
	operations on the text object:
	• All occurrences of “\XXX” will be replaced
	with the character “Y” (where XXX represents
	a number in the octal system and Y represents
	the ASCII equivalent of XXX). The valid range
	of octal values for this type of encoding is 0 to
	377. For example, the encoded text "http\72//"
	and "http\072//" will both be decoded to "http:/
	/", where the colon (:) is the ASCII equivalent
	of the octal value “72”.
	• All occurrences of “\xHH” will be replaced
	with the character “Y” (HH represents a
	number in the hexadecimal system and Y
	denotes the ASCII equivalent of HH. For
	example, the encoded text "http\x3a//" will be
	decoded to "http://", where the colon (:) is the
	ASCII equivalent of the hexadecimal value
	“3a“.
	• All occurrences of “\\uWWXX” will be
	replaced with the character sequence “YZ”
	(Where WW and XX represent two distinct
	hexadecimal values and Y and Z represent their
	ASCII equivalents of WW and XX respectively.
	For example, the encoded text "http%u3a2f/"
	and "http%u003a//" will both be decoded to
	"http://", where “3a” and “2f” are two
	hexadecimal values and the colon (:) and
	forward slash (“/”) represent their ASCII
	equivalents respectively.
	• All occurrences of "\b", "\n", "\t", "\f", and "\r"
	are replaced with the corresponding ASCII
	characters.
	If NO_BACKSLASH_ENCODED is specified,
	backslash decoding is not performed on the text
	object.
text.SET_TEXT_MODE(BAD_	Performs the associated undefined action if either
ENCODE_RAISE_UNDEFNO_BAD_	the URLENCODED or the BACKSLASH_
ENCODE_RAISE_UNDEF)	ENCODED mode is set and bad encoding
	corresponding to the specified encoding mode is
	encountered in the text object represented by text.
	If NO_BAD_ENCODE_RAISE_UNDEF is
	specified, the associated undefined action will not
	be performed when bad encoding is encountered in
	the text object represented by text.
