Product: ValidateXML command-line utility
ValidateXML is a simple xml validation tool that allows validating one or more xml files against DTD; either ones specified by the document itself, or against an alternative DTD specified via command line argument. Latter is often useful when either testing new versions of DTDs, or when original document does not contain a DTD reference.
