Frequently Asked Questions (3)

Q: What is XML validation?

A: XML validation checks if an XML document is well-formed (correct syntax) and valid (conforms to a specific schema or DTD).

A: XSD (XML Schema Definition) is more powerful and flexible than DTD, supporting data types, namespaces, and complex constraints.

Q: Why is my XML failing validation?
