XML is an acronym for Extensible Markup Language. It was designed with the objective of conveying and storing data while focusing on “what data is.”
The purpose of XML is to transport data. A framework for defining markup languages is provided by the XML standard. XML is both a programming language and a presentation language.
Case is important in XML. As a result, the uttermost core is required when constructing an XML script. It allows data to flow more easily between the application and the database. XML is more flexible since it enables for the design and use of custom tags. In XML, white space is kept. It is dynamic in nature since it transports data. The WWW consortium recommends XML. It’s a completely free open standard.
Advantages of Extensible Markup Language
- Because it supports Unicode, it can communicate practically any information in any written human language.
- It can represent common computer science data structures like records, lists, and trees.
- The structure, field names, and specific values are all specified in its self-documenting format.
- The required parsing algorithms are highly simple, efficient, and consistent due to the rigorous syntax and parsing constraints.
- XML is a popular document storage and processing format, both online and offline.
- They adheres to international guidelines.
- It is possible to upgrade it in stages.
- It facilitates unit testing, firewalls, acceptance testing, contractual specification, and software development by allowing validation utilizing schema languages such as XSD and Schematron.
- The hierarchical structure is appropriate for the majority (but not all) of document types.
- It is platform-independent, making it largely resistant to technological changes.
- Despite modifications in DTD (Document Type Definition) or Schema, maintaining forward and backward compatibility is pretty simple.
Disadvantages of XML
- Firstly, When compared to other text-based data transmission formats like JSON, XML syntax is verbose and redundant.
- When the volume of data is big, the redundancy in XML syntax generates increased storage and transportation costs.
- When compared to alternative text-based data transfer formats like JSON, an XML document is less understandable.
- Array not supported XML.
- Because of its verbose nature, XML file sizes are typically big; however, this is entirely dependent on who is writing it.
