Basic Knowledge

What is XSD (XML Schema)?

XSD is a specification that defines the structure of XML documents (what elements appear in what order and how many times) and their data types. It serves as a "data contract" between systems that exchange information via XML.

Why Use a Schema

With a schema, you can automatically validate that received data matches the agreed-upon format and reject invalid data before processing. An efficient approach is to auto-generate the schema foundation from actual XML and then manually refine the details.
