CDATASection object
The CDATASection object represents the CDATA section in the document.
The CDATASection interface is Text interface's subinterface, it does not define any of its own attributes or methods. Through Node interface inherits nodeValue attribute, or by accessing CharacterData interface inherits the data attribute, allowing access to the text content of the CDATA section.
Although CDATASection nodes can usually be treated as Text node processing, but note thatNode.normalize() method does not merge with adjacent CDATA sections.
Use Document.createCDATASection() Create a CDATASection.
CDATA sections contain text that is not parsed by the parser. Tags within CDATA sections are not considered as markup, and entities are not expanded. The main purpose is to include materials such as XML fragments without escaping all delimiters.
The only delimiter recognized within a CDATA is "]]>", which indicates the end of the CDATA section. CDATA sections cannot be nested.
