org::w3c::dom::EntityReference Class Reference
Inheritance diagram for org::w3c::dom::EntityReference:
List of all members.
EntityReference nodes may be used to represent an entity reference in the tree.
Note that character references and references to predefined entities are considered to be expanded by the HTML or XML processor so that characters are represented by their Unicode equivalent rather than by an entity reference. Moreover, the XML processor may completely expand references to entities while building the
Document, instead of providing
EntityReference nodes. If it does provide such nodes, then for an
EntityReference node that represents a reference to a known entity an
Entity exists, and the subtree of the
EntityReference node is a copy of the
Entity node subtree. However, the latter may not be true when an entity contains an unbound namespace prefix. In such a case, because the namespace prefix resolution depends on where the entity reference is, the descendants of the
EntityReference node may be bound to different namespace URIs. When an
EntityReference node represents a reference to an unknown entity, the node has no children and its replacement value, when used by
Attr.value for example, is empty.
EntityReference nodes and all their descendants are readonly. <p >Note:
EntityReference nodes may cause element content and attribute value normalization problems when, such as in XML 1.0 and XML Schema, the normalization is performed after entity reference are expanded.
