Properties

readonly

NamedNodeMap

entities

This
NamedNodeMap is a list of Entity objects declared in the
DTD and allows Entity objects to be
queried by name. Note that XML parameter entities are not included.
This NamedNodeMap is immutable -- its contents may not be altered.

readonly String internalSubset [DOM Level 2]

The
internal subset of the DTD (i.e., the portion of the DTD that appears
in the document itself rather than in an external file). The
delimiting square brackets of the internal subset are not part of the
returned value. If there is no internal subset, this property is
null.

readonly String name

The name of
the document type. This is the identifier that immediately follows
<!DOCTYPE> at the start of an XML document,
and it is the same as the tag name of the document's root
element.

readonly

NamedNodeMap

notations

A
NamedNodeMap that contains Notation objects representing all
notations declared in the DTD. It also allows Notation objects to be
looked up by notation name. This NamedNodeMap is immutable -- its
contents may not be altered.

readonly String publicId [DOM Level 2]

The public
identifier of the external subset of the DTD, or
null if none was specified.

readonly String systemId [DOM Level 2]

The system
identifier of the external subset of the DTD, or
null if none was specified.

Description

This infrequently used interface represents the DTD of an XML
document. Programmers working exclusively with HTML documents never
need to use this interface.

Because a DTD is not part of a document's content, DocumentType
nodes never appear in the document tree. If an XML document has a
DTD, the DocumentType node for that DTD is available through the
doctype property of the Document node.

DocumentType nodes are immutable and may not be modified in any way.
