CDATA Label Usage

The use of CDATA tags is seen in the XML file today,

Here's the answer: CDATA

The term CDATA refers to textual data (unparsed Character data) that should not be parsed by the XML parser.

In XML elements, "<" and "&" are illegal.

"<" generates an error because the parser interprets the character as the beginning of the new element.

"&" also generates an error because the parser interprets the character as the beginning of the character entity.

Some text, such as JavaScript code, contains a large number of "<" or "&" characters. To avoid errors, you can define the script code as CDATA.

All content in the CDATA section is ignored by the parser.

CDATA part by "<![ cdata["Start, End with"]]>":

<script><! [Cdata[function Matchwo (b) {if (a < b && a < 0) then  {  return 1;  } else  {  return 0;  }]] ></script>

In the example above, the parser ignores all the content in the CDATA section.

Comments about the CDATA section:

CDATA sections cannot contain the string "]]>". Also, nested CDATA sections are not allowed.

"]]>" that marks the end of a CDATA section cannot contain spaces or lines.
