XMLFormate

XMLFormate refers to the family of formats that use XML syntax to encode data and documents. They are text-based, platform-neutral, and designed for interoperable data exchange across organizations and systems. XML documents are structured as nested elements with attributes, and most variants rely on namespaces to avoid naming conflicts. Common encodings include UTF-8 and UTF-16.

Core standards and validation: XML 1.0 and 1.1 define the fundamental syntax. Documents can be validated against type definitions using DTDs, or against structural constraints with schema languages such as XML Schema (XSD) and RELAX NG. Validation helps ensure data conforms to a defined model, while parsing focuses on well-formedness.

Examples of XML formats: XML-based web services definitions (WSDL), messaging protocols (SOAP), feed formats (RSS, Atom), vector graphics (SVG), and document formats (Office Open XML, XHTML). Others include MathML, COLLADA, and various industry-specific schemas. Many formats are further transformed or serialized by languages such as XSLT to produce other XML or non-XML outputs.

Processing and use: XML formats are processed by parsers using DOM, SAX, or streaming APIs (StAX). They support modular data through namespaces and modular schemas. Pros include readability, extensibility, and strong tooling support; cons include verbosity and potential processing overhead. Security considerations include avoiding external entity processing (XXE) and ensuring robust validation.
