Remarks

This object represents an entity from a Document Type Declaration (DTD). Entities are declarations of abbreviated text or other nodes within an XML document. These can then be inserted at various places in an XML document with EntityReference objects.

While the entity name is stored in the Node.nodeName property, the rest of the entity's data (the actual content of the entity) is stored as children of this object (in the Node.childNodes property). The Node.parentNode for Entity nodes will always be null.

Entity objects are read-only and cannot be modified once they are added to the document or after a document is loaded. If you need to change an entity's contents you should create a new one and change all the EntityReference nodes that referred to the old entity to refer to the new one instead.
