XMLdokumentumok

XMLdokumentumok, or XML documents, are files that store and transport data using the Extensible Markup Language (XML). XML is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It is designed to be self-descriptive, meaning that the structure of the data is defined within the document itself.

XML documents consist of a tree structure of elements, each represented by a pair of tags. An element can contain other elements, text, or both. Elements can also have attributes, which provide additional information about the element. XML documents are often used to exchange data between different systems, as the structure of the data is explicitly defined and can be easily parsed by various programming languages.

One of the key features of XML is its extensibility. Users can define their own tags and attributes, allowing for the creation of custom data structures tailored to specific needs. This makes XML a versatile format for a wide range of applications, from web services and data interchange to configuration files and document storage.

XML documents can be validated against a Document Type Definition (DTD) or an XML Schema to ensure that they conform to a specific structure and data type. This validation process helps maintain data integrity and consistency across different systems.

In summary, XMLdokumentumok are a fundamental technology for data interchange and storage, offering a flexible and extensible format for representing structured information. Their widespread use and support in various programming languages and tools make them an essential component of modern software development and data management.
