/***************************************************************** Interface: Node Desc: From the DOM spec: TheNode
interface is the primary datatype for the entire Document Object Model. It represents a single node in the document tree. While all objects implementing theNode
interface expose methods for dealing with children, not all objects implementing theNode
interface may have children. For example,Text
nodes may not have children, and adding children to such nodes results in aDOMException
being raised.The attributes
nodeName
,nodeValue
andattributes
are included as a mechanism to get at node information without casting down to the specific derived interface. In cases where there is no obvious mapping of these attributes for a specificnodeType
(e.g.,nodeValue
for an Element orattributes
for a Comment), this returnsnull
. Note that the specialized interfaces may contain additional and more convenient mechanisms to get and set the relevant information. Notes: This C/C++ binding adds the following methods to the DOM level 1 specified methods: void enableExceptions(int enable); DOMException * getLastError(); void destroy(); *****************************************************************/Method: Node::getNodeName

interface represents the entire HTML or XML document. Conceptually, it is the root of the document tree, and provides the primary access to the document's data.Since elements, text nodes, comments, processing instructions, etc. cannot exist outside the context of a

is a "lightweight" or "minimal"Document
object. It is very common to want to be able to extract a portion of a document's tree or to create a new fragment of a document. Imagine implementing a user command like cut or rearranging a document by moving fragments around. It is desirable to have an object which can hold such fragments and it is quite natural to use a Node for this purpose. While it is true that aDocument
object could fulfil this role, aDocument
object can potentially be a heavyweight object, depending on the underlying implementation. What is really needed for this is a very lightweight object.DocumentFragment
is such an object.Furthermore, various operations -- such as inserting nodes as children of another
Node
-- may takeDocumentFragment
objects as arguments; this results in all the child nodes of theDocumentFragment
being moved to the child list of this node.The children of a
DocumentFragment
node are zero or more nodes representing the tops of any sub-trees defining the structure of the document.DocumentFragment
nodes do not need to be well-formed XML documents (although they do need to follow the rules imposed upon well-formed XML parsed entities, which can have multiple top nodes). For example, aDocumentFragment
might have only one child and that child node could be aText
node. Such a structure model represents neither an HTML document nor a well-formed XML document.When a
DocumentFragment
is inserted into aDocument
(or indeed any otherNode
that may take children) the children of theDocumentFragment
and not theDocumentFragment
itself are inserted into theNode
. This makes theDocumentFragment
very useful when the user wishes to create nodes that are siblings; theDocumentFragment
acts as the parent of these nodes so that the user can use the standard methods from theNode
interface, such asinsertBefore()
andappendChild()
. Notes: *****************************************************************/

nodes. Assume the following XML document:<elementExample id="demo"> <subelement1/> <subelement2><subsubelement/></subelement2> </elementExample>When represented using DOM, the top node is an
Element
node for "elementExample", which contains two childElement
nodes, one for "subelement1" and one for "subelement2". "subelement1" contains no child nodes.Elements may have attributes associated with them; since the
Element
interface inherits fromNode
, the genericNode
interface methodgetAttributes
may be used to retrieve the set of all attributes for an element. There are methods on theElement
interface to retrieve either anAttr
object by name or an attribute value by name. In XML, where an attribute value may contain entity references, anAttr
object should be retrieved to examine the possibly fairly complex sub-tree representing the attribute value. On the other hand, in HTML, where all attributes have simple string values, methods to directly access an attribute value can safely be used as a convenience.

Inherits from Node/***************************************************************** Interface: Attr Desc: From the DOM spec: TheAttr
interface represents an attribute in anElement
object.Typically the allowable values for the attribute are defined in a documenttype definition.
Attr
objects inherit theNode
interface, but since they are not actually child nodes of the element they describe, the DOM does not consider them part of the document tree. Thus, theNode
attributesparentNode
,previousSibling
, andnextSibling
have a null value forAttr
objects. The DOM takes the view that attributes are properties of elements rather than having a separate identity from the elements they are associated with; this should make it more efficient to implement such features as default attributes associated with all elements of a given type. Furthermore,Attr
nodes may not be immediate children of aDocumentFragment
. However, they can be associated withElement
nodes contained within aDocumentFragment
. In short, users and implementors of the DOM need to be aware thatAttr
nodes have some things in common with other objects inheriting theNode
interface, but they also are quite distinct.The attribute's effective value is determined as follows: if this attribute has been explicitly assigned any value, that value is the attribute's effective value; otherwise, if there is a declaration for this attribute, and that declaration includes a default value, then that default value is the attribute's effective value; otherwise, the attribute does not exist on this element in the structure model until it has been explicitly added. Note that the
nodeValue
attribute on theAttr
instance can also be used to retrieve the string version of the attribute's value(s).In XML, where the value of an attribute can contain entity references, the child nodes of the
Attr
node provide a representation in which entity references are not expanded. These child nodes may be eitherText
orEntityReference
nodes. Because the attribute type may be unknown, there are no tokenized attribute values. Notes: *****************************************************************/Method: Attr::getName

Note that the // implementation is in charge of this attribute, not the user. If // the user changes the value of the attribute (even if it ends up // having the same value as the default value) then the specified // flag is automatically flipped to TRUE. To re-specify the // attribute as the default value from the DTD, the user must delete // the attribute. The implementation will then make a new attribute // available with the specified flag set to false and the default // value (if one exists). // // Notes: //========================================================================= C++ Signature int Attr::getSpecified( );Method: Attr::getValue

Inherits from CharacterData/***************************************************************** Interface: Text Desc: From the DOM spec: TheText
interface represents the textual content (termed character data in XML) of anElement
orAttr
. If there is no markup inside an element's content, the text is contained in a single object implementing theText
interface that is the only child of the element. If there is markup, it is parsed into a list of elements andText
nodes that form the list of children of the element.When a document is first made available via the DOM, there is only one
Text
node for each block of text. Users may create adjacentText
nodes that represent the contents of a given element without any intervening markup, but should be aware that there is no way to represent the separations between these nodes in XML or HTML, so they will not (in general) persist between DOM editing sessions. Thenormalize()
method onElement
merges any such adjacentText
objects into a single node for each block of text; this is recommended before employing operations that depend on a particular document structure, such as navigation withXPointers.
Notes: *****************************************************************/Method: Text::splitText
//========================================================================= // Method: splitText // Desc: Breaks this Text node into two Text nodes at the specified // offset, keeping both in the tree as siblings.

Inherits from Text/***************************************************************** Interface: CDATASection Desc: From the DOM spec: CDATA sections are used to escape blocks of text containing characters that would otherwise be regarded as markup. The only delimiter that is recognized in a CDATA section is the "]]>" string that ends the CDATA section. CDATA sections can not be nested. The primary purpose is for including material such as XML fragments, without needing to escape all the delimiters.The
DOMString
attribute of theText
node holds the text that is contained by the CDATA section. Note that this may contain characters that need to be escaped outside of CDATA sections and that, depending on the character encoding ("charset") chosen for serialization, it may be impossible to write out some characters as part of a CDATA section.The
CDATASection
interface inherits theCharacterData
interface through theText
interface. AdjacentCDATASections
nodes are not merged by use of the Element.normalize() method. Notes: *****************************************************************/

'. Note that this is the definition of a comment in XML, and, in practice, HTML, although some HTML tools may implement the full SGML comment structure. Notes: *****************************************************************/

has adoctype
attribute whose value is eithernull
or aDocumentType
object. TheDocumentType
interface in the DOM Level 1 Core provides an interface to the list of entities that are defined for the document, and little else because the effect of namespaces and the various XML scheme efforts on DTD representation are not clearly understood as of this writing.The DOM Level 1 doesn't support editing
DocumentType
nodes. Notes: *****************************************************************/Method: DocumentType::getName
//========================================================================= // Method: getName // Desc: The name of the DTD; i.e., the name immediately following the // DOCTYPE keyword. // // Notes: //========================================================================= C++ Signature const unicode * DocumentType::getName( );Method: DocumentType::getEntities
//========================================================================= // Method: getEntities // Desc: Return a NamedNodeMap containing the general entities, both // external and internal, declared in the DTD. Duplicates are // discarded. Every Node in this map also implements the Entity // interface. // // Notes: Note that the returned NamedNodeMap belongs to this node. No // attempt must be made to delete it. //========================================================================= C++ Signature NamedNodeMap * DocumentType::getEntities( );Method: DocumentType::getNotations
//========================================================================= // Method: getNotations // Desc: Return a NamedNodeMap containing the notations declared in the // DTD.

No // attempt must be made to delete it. //========================================================================= C++ Signature NamedNodeMap * DocumentType::getNotations( );
/***************************************************************** Interface: DOMImplementation Desc: From the DOM spec: TheDOMImplementation
interface provides a number of methods for performing operations that are independent of any particular instance of the document object model.The DOM Level 1 does not specify a way of creating a document instance, and hence document creation is an operation specific to an implementation. Future Levels of the DOM specification are expected to provide methods for creating documents directly. Notes: *****************************************************************/
Method: DOMImplementation::hasFeature
//========================================================================= // Method: hasFeature // Desc: Test if the DOM implementation implements a specific feature. // // Notes: In Level 1, the legal value for feature are "HTML" and "XML" // (case insensitive). In Level 1 this is the string "1.0". If the // version is not specified, supporting any version of the feature // will cause the method to return non-zero (TRUE). //========================================================================= C++ Signature int DOMImplementation::hasFeature( const unicode * feature, //The package name of the feature to test const unicode * version //The version number of the package name to test );
Inherits from Node/***************************************************************** Interface: Entity Desc: From the DOM spec: 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 fromNode
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 thechildNodes
method on theEntity
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 anEntity
, every relatedEntityReference
node has to be replaced in the structure model by a clone of theEntity
's contents, and then the desired changes must be made to each of those clones instead. All the descendants of anEntity
node are readonly.An
Entity
node does not have any parent. Notes: *****************************************************************/Method: Entity::getPublicId
//========================================================================= // Method: getPublicId // Desc: Return the public identifier associated with the entity, if // specified. If the public identifier was not specified, this is // null. // // Notes: //========================================================================= C++ Signature const unicode * Entity::getPublicId( );Method: Entity::getSystemId
//========================================================================= // Method: getSystemId // Desc: Return the system identifier associated with the entity, if // specified. If the system identifier was not specified, this is // null. // // Notes: //========================================================================= C++ Signature const unicode * Entity::getSystemId( );Method: Entity::getNotationName
//========================================================================= // Method: getNotationName // Desc: For unparsed entities, the name of the notation for the entity. // For parsed entities, this is null. // // Notes: //========================================================================= C++ Signature const unicode * Entity::getNotationName( );
Inherits from Node/***************************************************************** Interface: EntityReference Desc: From the DOM spec: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 providingEntityReference
objects. If it does provide such objects, then for a givenEntityReference
node, it may be that there is noEntity
node representing the referenced entity; but if such anEntity
exists, then the child list of theEntityReference
node is the same as that of theEntity
node. As with theEntity
node, all descendants of theEntityReference
are readonly.The resolution of the children of the
EntityReference
(the replacement value of the referencedEntity
) may be lazily evaluated; actions by the user (such as calling thechildNodes
method on theEntityReference
node) are assumed to trigger the evaluation. Notes: *****************************************************************/
Inherits from Node/***************************************************************** Interface: Notation Desc: From the DOM spec: This interface represents a notation declared in the DTD. A notation either declares, by name, the format of an unparsed entity (see section 4.7 of the XML 1.0 specification), or is used for formal declaration of Processing Instruction targets (see section 2.6 of the XML 1.0 specification). ThenodeName
attribute inherited fromNode
is set to the declared name of the notation.The DOM Level 1 does not support editing
Notation
nodes; they are therefore readonly.A
Notation
node does not have any parent. Notes: *****************************************************************/Method: Notation::getPublicId
//========================================================================= // Method: getPublicId // Desc: The public identifier of this notation. If the public identifier // was not specified, this is null. // // Notes: //========================================================================= C++ Signature const unicode * Entity::getPublicId( );Method: Notation::getSystemId
//========================================================================= // Method: getSystemId // Desc: The system identifier of this notation. If the system identifier // was not specified, this is null. // // Notes: //========================================================================= C++ Signature const unicode * Entity::getSystemId( );
/***************************************************************** Interface: NamedNodeMap Desc: From the DOM spec: Objects implementing theNamedNodeMap
interface are used to represent collections of nodes that can be accessed by name. Note thatNamedNodeMap
does not inherit fromNodeList
;NamedNodeMap
s are not maintained in any particular order. Objects contained in an object implementingNamedNodeMap
may also be accessed by an ordinal index, but this is simply to allow convenient enumeration of the contents of aNamedNodeMap
, and does not imply that the DOM specifies an order to these Nodes. Notes: *****************************************************************/Method: NamedNodeMap::getNamedItem
//========================================================================= // Method: getNamedItem // Desc: Retrieves a node specified by name. // // Notes: //========================================================================= C++ Signature Node * NamedNodeMap::getNamedItem( const unicode * name //Name of a node to retrieve );Method: NamedNodeMap::setNamedItem

//========================================================================= // Method: removedNamedItem // Desc: Removes a node specified by name. If the removed node is an // Attr with a default value it is immediately replaced. // // DOMException registered or thrown: // NO_MODIFICATION_ALLOWED_ERR if NamedNodeMap is read only // NOT_FOUND_ERR if no Node with name is in map // // Notes: //========================================================================= C++ Signature Node * NamedNodeMap::removeNamedItem( const unicode * name );Method: NamedNodeMap::item
//========================================================================= // Method: item // Desc: Returns the "index"th item in the map.

/***************************************************************** Interface: NodeList Desc: From the DOM spec: TheNodeList
interface provides the abstraction of an ordered collection of nodes, without defining or constraining how this collection is implemented.The items in the
NodeList
are accessible via an integral index, starting from 0. Notes: Non-DOM method: destroy() *****************************************************************/Method: NodeList::item
//========================================================================= // Method: item // Desc: Returns the "index"th item in the list.

This must be called when the NodeList // is no longer needed. // // Notes: C/C++ extension to DOM level 1 //========================================================================= C++ Signature void Node::destroy( );
/***************************************************************** Interface: DOMException Desc: From the DOM spec: DOM operations only raise exceptions in "exceptional" circumstances, i.e., when an operation is impossible to perform (either for logical reasons, because data is lost, or because the implementation has become unstable). In general, DOM methods return specific error values in ordinary processing situation, such as out-of-bound errors when usingNodeList
.Implementations may raise other exceptions under other circumstances. For example, implementations may raise an implementation-dependent exception if a
null
argument is passed.Some languages and object systems do not support the concept of exceptions. For such systems, error conditions may be indicated using native error reporting mechanisms. For some bindings, for example, methods may return error codes similar to those listed in the corresponding method descriptions.
