HTML vs XML
HTML
HTML stands for HyperText Markup Language which is a language used to describe the structure of a web page. It consists of various HTML element which is composed of HTML tags and their content.
HTML is a hypertext language so we can create a chain of links of documents. The current version of HTML is HTML5. HTML is static and it can ignore small errors and in it, closing tags are not necessary.
Let us see an example of HTML −
Example
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>HTML</title> </head> <body> <h1 style="text-align: center;color:#db133a;">HTML</h1> <h3 style="text-align: center;">I'm a HTML document.</h3> </body> </html>

XML
XML stands for eXtensible Markup Language which is a language used to transfer data not to structure data. It is dynamic and it reports all errors and in its closing tags are necessary.

<?xml version="1.0" encoding="UTF-8"?> <fullname> <firstname>John</firstname> <lastname>Miller</lastname> </fullname>
