XML اسئلة واجوبة المقابلات

Question: What is XML?

• XML is the Extensible Markup Language. It improves the functionality of the Web by letting you identify your information in a more accurate, flexible, and adaptable way.
• It is extensible because it is not a fixed format like HTML (which is a single, predefined markup language). 
• Instead, XML is actually a metalanguage, a language for describing other languages which lets you design your own markup languages for limitless different types of documents. 
• XML can do this because it's written in SGML, the international standard metalanguage for text document markup (ISO 8879).
