XML schema validation

XML schema validation is a process that ensures an XML document, which is a structured data file, follows specific rules defined by a schema. The schema acts like a blueprint, outlining what elements and data types are allowed and how they should be organized. Validation checks the XML document against these rules to confirm it is correctly structured and contains valid data. This helps maintain consistency, accuracy, and reliability across data exchanges, making sure the information adheres to agreed standards before it is used or shared.
