Validating an XML file against DTD definitions

A Document Type Definition (DTD) defines the document structure of an XML document with a list of elements and attributes. Kettle provides the DTD Validator entry job to do a validation against a DTD definition file.

For example, suppose you have an XML file with museums information, as follows:

<museums>
    <museum>
       <name>Fundacion Federico Klemm</name> 
       <city>Buenos Aires</city>
       <country>Argentina</country> 
   </museum>
    <museum id_museum= '2'> 
        <name>Fundacion Proa</name>
        <city>Buenos Aires</city> 
        <country>Argentina</country> 
   </museum>
   <museum id_museum= '9'> 
        <name>Museu Nacional de Belas Artes</name>
         <country>Brazil</country> 
   </museum>
   <museum id_museum= '19'> 
      <name>Biblioteca Luis Angel Arango</name...
