XML Schema, also known as XML Schema Definition (XSD), is a language used to describe and validate the structure and content of an XML document. It defines the legal building blocks, order, and data types for elements and attributes, acting as a blueprint or contract for XML data interchange.
Key Purposes and Advantages
Validation: An XML document validated against a schema is considered "valid" and "well-formed," ensuring it adheres to a specific set of rules beyond basic XML syntax.
Data Integrity: Schemas enforce data types (e.g., xs:integer, xs:date, xs:string), ranges, patterns, and other constraints, which helps prevent errors and ensures data correctness and consistency.
Data Interchange: Independent groups of people can agree on a standard schema for interchanging data, ensuring all parties have the same expectations about the content format.
Tool Support: Because schemas are written in XML syntax, the same tools (editors, parsers, DOM, XSLT processors) can be used to work with both XML documents and their schemas.
