XML::DOM::EntityReference - An XML ENTITY reference in XML::DOM
XML::DOM::EntityReference extends XML::DOM::Node.
EntityReference objects may be inserted into the structure model
when an entity reference is in the source document, or when the user wishes
to insert an entity reference. 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 structure model,
instead of providing EntityReference objects. If it does provide such
objects, then for a given EntityReference node, it may be that there is no
Entity node representing the referenced entity; but if such an Entity
exists, then the child list of the EntityReference node is the same as that
of the Entity node. As with the Entity node, all descendants of the
EntityReference are readonly.
The resolution of the children of the EntityReference (the
replacement value of the referenced Entity) may be lazily evaluated; actions
by the user (such as calling the childNodes method on the EntityReference
node) are assumed to trigger the evaluation.
