public interface DocumentType extends Node
Document has a
doctype attribute whose value is either
null or a
DocumentType object. The
DocumentType interface in the DOM Core provides an interface to the list of entities that are defined for the document, and little else because the effect of namespaces and the various XML schema efforts on DTD representation are not clearly understood as of this writing.
DOM Level 3 doesn't support editing
DocumentType nodes are read-only.

The name of DTD; i.e., the name immediately following the
NamedNodeMap containing the general entities, both external and internal, declared in the DTD. Parameter entities are not contained. Duplicates are discarded. For example in:
<!DOCTYPE ex SYSTEM "ex.dtd" [ <!ENTITY foo "foo"> <!ENTITY bar "bar"> <!ENTITY bar "bar2"> <!ENTITY % baz "baz"> ]> <ex/>the interface provides access to
fooand the first declaration of
barbut not the second declaration of
baz. Every node in this map also implements the
entitiescannot be altered in any way.
NamedNodeMap containing the notations declared in the DTD. Duplicates are discarded. Every node in this map also implements the
The DOM Level 2 does not support editing notations, therefore
notations cannot be altered in any way.
The public identifier of the external subset.
The system identifier of the external subset. This may be an absolute URI or not.
The internal subset as a string, or
null if there is none. This is does not contain the delimiting square brackets.
Note: The actual content returned depends on how much information is available to the implementation. This may vary depending on various parameters, including the XML processor used to build the document.
