XML (Extensible Markup Language) is a markup language that stores and provides information in a structured and web-centric manner. As a web-based application language, it has seen widespread use and is sometimes subject to misconceptions. Here are some facts that aren't true about XML:
XML is Not a Programming Language
XML is not a programming language, nor does it contain specific instructions. Instead, XML functions as a form of metadata that stores information and provides instructions to browsers, APIs, and languages on how to process that information. XML is neither compiled nor interpreted, and its purpose is not to communicate directly with users.
XML Cannot Be Programmed
Contrary to popular belief, XML cannot be programmed. While it does provide the structure for storing and transferring information between platforms, it does not contain the commands or instructions required for the programming of the data within it. For example, you can store information in an XML file, but you cannot program a computer to search for a certain element or set of elements within that file without first defining a specific algorithm to do that.
XML Does Not Require a Specific Format
XML does not require a specific format and developers can:
- create their own custom tags;
- use tags that are associated with a particular application such as a web service or application programming interface (API);
- use industry standard tags for data such as eXtensible Business Reporting Language (XBRL);
- or use tags from a specific language or platform such as XML Schema Definition (XSD).
XML Does Not Control the Data It Contains
XML is not a language used to control the data contained within it but is instead a language used to store and transfer data. XML simply stores the data in a structured format and provides a way to request and retrieve the data.
XML Is Not Compulsory
XML is not mandatory to be used in all applications and its use depends wholly on the needs of the application and how it’s to be utilized. Some applications may require a type of structured data while others may utilize complex coding logics and algorithms. Therefore, there is no one-size-fits-all approach and XML is only one of many options available.
FAQ
What is XML used for?
XML is used for storing and transferring structured data. It is usually used between web applications to facilitate the exchange of data.
What is the difference between XML and HTML?
HTML is a markup language used to display content in web browsers, while XML is a markup language used to store and transport data.
Does all web development involve XML?
No, not all web development requires to involve XML. It depends on the specific needs of the application and the type of structured data that is to be utilized.
What is the purpose of XML?
The purpose of XML is to store and transfer data between applications in a structured format that can be easily read and understood.
Does XML support data encoding?
Yes, XML supports data encoding and can be used to create and store data that is encoded using base64, hexadecimal, or other types of encoding.
