XML Interview Questions and Answers

Question: What is XML?
Answer:
  • 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).
