public interface Entity extends Node
This interface represents a known entity, either parsed or unparsed, in an XML document. Note that this models the entity itself not the entity declaration.The
nodeName
attribute that is inherited fromNode
contains the name of the entity.An XML processor may choose to completely expand entities before the structure model is passed to the DOM; in this case there will be no
EntityReference
nodes in the document tree.XML does not mandate that a non-validating XML processor read and process entity declarations made in the external subset or declared in parameter entities. This means that parsed entities declared in the external subset need not be expanded by some classes of applications, and that the replacement text of the entity may not be available. When the replacement text is available, the corresponding
Entity
node's child list represents the structure of that replacement value. Otherwise, the child list is empty.DOM Level 3 does not support editing
Entity
nodes; if a user wants to make changes to the contents of anEntity
, every relatedEntityReference
node has to be replaced in the structure model by a clone of theEntity
's contents, and then the desired changes must be made to each of those clones instead.Entity
nodes and all their descendants are readonly.An
Entity
node does not have any parent.Note: If the entity contains an unbound namespace prefix, the
namespaceURI
of the corresponding node in theEntity
node subtree isnull
. The same is true forEntityReference
nodes that refer to this entity, when they are created using thecreateEntityReference
method of theDocument
interface.See also the Document Object Model (DOM) Level 3 Core Specification.
