XML comments are just like HTML comments. We know that the comments are used to make codes more understandable other developers.
XML Comments add notes or lines for understanding the purpose of an XML code. Although XML is known as self-describing data but sometimes XML comments are necessary.
An XML comment should be written as:
<!-- Write your comment-->
Let's take an example to show the use of comment in an XML example:
<?xml version="1.0" encoding="UTF-8" ?> <!--Students marks are uploaded by months--> <students> <student> <name>Ratan</name> <marks>70</marks> </student> <student> <name>Aryan</name> <marks>60</marks> </student> </students>
