what is a xml file

An XML file is a file format used for storing, transmitting, and reconstructing arbitrary data. It contains tags that define not only how the document should be structured but also how it should be stored and transported over the internet. XML stands for Extensible Markup Language and was designed to be both human-readable and machine-readable. It is a markup language much like HTML, but it was designed to store and transport data. XML is a software- and hardware-independent tool for storing and transporting data. XML files are used as the basis for various document formats, including RSS, Microsoft .NET configuration files, and Microsoft Office files. XML files can be opened and edited with text editors, web browsers, online editors, and application-specific programs. To summarize, an XML file is a file used to store data in the form of hierarchical elements, and data stored in XML files can be read by computer programs with the help of custom tags, which indicate the type of element.
