Interface DocumentType

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.

public 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

public String getName()

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

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.

public String getPublicId()

The public identifier of the external subset.

Since:

DOM Level 2

public String getSystemId()

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