namespace Poco {
namespace XML {
class XML_API Entity: public AbstractContainerNode
This interface represents an entity, either parsed or unparsed, in an XML
document. Note that this models the entity itself not the entity declaration.
Entity declaration modeling has been left for a later Level of the DOM
specification.
The 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 external
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 value of the entity may not be available. When the replacement
value is available, the corresponding Entity node's child list represents
the structure of that replacement text. Otherwise, the child list is empty.
The resolution of the children of the Entity (the replacement value) may
be lazily evaluated; actions by the user (such as calling the childNodes
method on the Entity Node) are assumed to trigger the evaluation.
The DOM Level 1 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.
An Entity node does not have any parent.
{
public:
const XMLString& publicId() const;
Returns the public identifier associated with
the entity, if specified. If the public identifier
was not specified, this is the empty string.
const XMLString& systemId() const;
Returns the system identifier associated with
the entity, if specified. If the system identifier
was not specified, this is the empty string.
const XMLString& notationName() const;
Returns, for unparsed entities, the name of the
notation for the entity. For parsed entities, this
is the empty string.
