XML (eXtensible Markup Language) is a versatile format for structuring data. Here's a quick guide to help you understand its basics!

What is XML?

XML is a markup language similar to HTML, but designed for storing and transporting data rather than displaying it.

  • Key Features:
    • Self-descriptive tags
    • Hierarchical data organization
    • Platform-independent

XML Syntax Basics

A simple XML document looks like this:

<?xml version="1.0" encoding="UTF-8"?>  
<note>  
  <to>Alice</to>  
  <from>Bob</from>  
  <body>Reminder: Meeting at 3 PM.</body>  
</note>  
  • Rules to Remember:
    • Tags are case-sensitive (<To><to>)
    • Proper nesting is required
    • Attributes must be quoted
