What is XML?
XML stands for Extensible Markup Language and like HTML, is used to format and present information. However, unlike HTML, it does not have a fixed set of formatted tags but instead acts as a meta-language.
How does XML work?
XML is used to structure data in a way that both machines and humans can easily read it. Several types of documents use the XML syntax, including RSS feeds, Microsoft Office’s latest document formats, and Apple iWork.
XML is extremely flexible, allowing users to create and nest their own tags and attributes. Developers create and develop many interfaces to help easily process XML data.
