DTD Validator

A DTD Validator is a tool that checks whether a document, typically an XML file, conforms to a set of rules defined in a Document Type Definition (DTD). Think of the DTD as a blueprint that specifies the structure, elements, and attributes the document should have. The validator ensures your document follows this blueprint, catching errors like missing elements or incorrect order, which helps maintain consistency and correctness. Essentially, it verifies that your XML document is well-formed and meets the predefined standards set by the DTD.
