Interface DocumentType

All Superinterfaces:: Node

public interface DocumentType
extends Node

Each 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. DocumentType nodes are read-only.

Method Summary

NamedNodeMap getEntities()
          A NamedNodeMap containing the general entities, both external and internal, declared in the DTD.

java.lang.String getInternalSubset()
          The internal subset as a string, or null if there is none.

java.lang.String getName()
          The name of DTD; i.e., the name immediately following the DOCTYPE keyword.

NamedNodeMap getNotations()
          A NamedNodeMap containing the notations declared in the DTD.

java.lang.String getPublicId()
          The public identifier of the external subset.

java.lang.String getSystemId()
          The system identifier of the external subset.

Method Detail

getName

public java.lang.String getName()

The name of DTD; i.e., the name immediately following the DOCTYPE keyword.

getEntities

public NamedNodeMap getEntities()

A 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 foo and the first declaration of bar but not the second declaration of bar or baz. Every node in this map also implements the Entity interface.
The DOM Level 2 does not support editing entities, therefore entities cannot be altered in any way.

getNotations

public NamedNodeMap getNotations()

A NamedNodeMap containing the notations declared in the DTD. Duplicates are discarded. Every node in this map also implements the Notation interface.
The DOM Level 2 does not support editing notations, therefore notations cannot be altered in any way.

getPublicId

public java.lang.String getPublicId()

The public identifier of the external subset.

Since:: DOM Level 2

getSystemId

public java.lang.String getSystemId()

The system identifier of the external subset. This may be an absolute URI or not.

Since:: DOM Level 2

getInternalSubset

public java.lang.String getInternalSubset()

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.

Since:: DOM Level 2
