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.
nodeName attribute that is inherited from
Node 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 an
Entity, every related
EntityReference node has to be replaced in the structure model by a clone of the
Entity's contents, and then the desired changes must be made to each of those clones instead.
Entity nodes and all their descendants are readonly.
Entity node does not have any parent.
Note: If the entity contains an unbound namespace prefix, the
namespaceURI of the corresponding node in the
Entity node subtree is
null. The same is true for
EntityReference nodes that refer to this entity, when they are created using the
createEntityReference method of the
