I worked a bit with IBMs xml4j.  In theParser Class, you can find the
method
     readDTD()
to open a DTD.

For questions like
- Can an element x be inserteted as the child of  y
Have a look at the mehtods of the DTD class.

The DTD class offers for example two methods
     getInsertableElement()
     getappendableElement()
to check which elements can be inserted at position or appended for
an element. It offers also methods to extract element declaration
     getElementDeclaration()
     getElementDeclarations()
or Attribut Declaration (of a specific element)
     getAttributDelcarations()
     getAttributDeclaration()

Subject:  XML DTD parser




1. Can someone please point me to a XML DTD parser?
2. In my application I want to be able to open an instance of
    the document's DTD independently so that I can query it.
    For me queries like the following would be pertinent :
    -  What all elements are defined by the DTD?
    -  Can an element 'x' be inserted as the child of 'y'?
    -  What attributes are allowed by an element 'x'?
    -  etc ...
    Is there a way to do this using any SAX parser? If not
    how do I go about achieving this?
thanks,
