Methods used with cdata tags:
CDATA
The term CDATA refers to the Text data parsed by the XML parser (Unparsed Character Data).
In XML elements, "<" and "&" are illegal.
"<" will generate an error because the parser will interpret this character as the beginning of a new element.
"&" will also generate an error because the parser will interpret this character as the beginning of a character entity.
Some text, such as JavaScript code, contains a large number of "<" or "&" characters. To avoid errors, the script code can be defined as CDATA.
Everything within the CDATA section will be ignored by the parser.
The CDATA part starts with "" and ends with "":
In the above example, the parser will Ignore everything in the CDATA section.
Notes on the CDATA part:
The CDATA part cannot contain the string "]]>". Nested CDATA sections are also not allowed.
The "]]>" marking the end of the CDATA section cannot contain spaces or line breaks.
