What is XML?
XML stands for Extensible Markup Language. It is a markup language that is used to encode documents in a format that is both human-readable and machine-readable. XML is often used to store and transport data between different systems and applications.
In XML, data is enclosed in tags that define the structure and meaning of the data. XML is often used in conjunction with other technologies, such as XSLT (Extensible Stylesheet Language Transformations) for transforming XML data into different formats, or SOAP (Simple Object Access Protocol) for exchanging XML-based messages between web services.
- XML is a markup language that was first introduced in 1998 by the World Wide Web Consortium (W3C), a standards organization that develops web technologies.
- XML is a text-based format, which means that XML documents are stored as plain text files that can be edited and read by humans.
- XML is a flexible format that can be used to represent many different types of data. For example, it can be used to represent documents, databases, and configuration files.
- XML documents are made up of elements, which are enclosed in tags. Elements can contain other elements, as well as attributes, which provide additional information about the element.
- XML is often used to represent data in a hierarchical structure, with elements nested inside other elements to create a tree-like structure.
- XML can be validated using a schema or a DTD (Document Type Definition), which defines the rules for the structure and content of an XML document.
- XML is often used for data exchange between different systems and applications, because it provides a standard way of representing data that can be easily understood by both humans and machines.
- XML can be transformed into other formats using XSLT, which allows developers to create stylesheets that can convert XML data into HTML, PDF, or other formats.
