Basic XML Knowledge

• What is XML? XML (eXtensible Markup Language) is a markup language used to mark electronic documents so that they are structured. It is designed to transport and store data, with a focus on what data is.
• Difference from HTML: HTML was designed to display data (like web page layout), while XML was designed to transport and store data. HTML has predefined tags (like <p>, <div>), while XML tags are defined by the author (like <person>, <name>).
• Tree Structure: XML documents form a tree structure that must contain a Root Element, which is the parent of all other elements.
• Strict Syntax Rules: XML must have closing tags, is case-sensitive, and tags must be properly nested. Any syntax error will cause the XML parser to report an error and stop parsing.
