XML FILES

An XML (Extensible Markup Language) file is a text-based document that uses a set of rules to encode data, allowing for both human and machine readability. It's similar to HTML, but with the key difference that XML uses custom tags defined by the user, while HTML uses predefined tags. This makes XML highly versatile for storing and exchanging data in various formats. 

Here's a more detailed look: 

• Purpose:
  XML is designed for storing and transporting data in a structured, self-descriptive format. It's not meant to display information on its own but rather to hold data that can be processed by applications. 
  
• Structure:
  XML documents consist of elements (data enclosed in tags), attributes (data within tags), and text. 
  
• Human and Machine Readable:
  XML is designed to be easily understood by both humans and computers. 
  
• Versatility:
  XML can be used for a wide variety of applications, including storing app configuration data, exchanging data between databases, and representing structured information. 
  
• Opening and Editing:
  You can open and edit XML files using any text editor, like Notepad or Notepad++, according to freeCodeCamp. 
  
• XML and HTML:
  While both are markup languages, HTML is primarily for displaying content, while XML focuses on storing and transporting data.
