Attribute Description Property Type Readonly Description attributes * Object true A collection containing the attributes of this node (if it is an Element) or null otherwise. baseURI * String true The absolute base URI of this node or null if the implementation wasn't able to obtain an absolute URI. childNodes * NodeList true A NodeList that contains all direct children of this node. data String false Data of the instruction. firstChild * Node true Retrieves a reference to the first child for the object. lastChild * Node true Retrieves a reference to the last child for the object. localName * String true Retrieves the local name of node. namespaceURI * String true Retrieves the namespace URI. nextSibling * Node true Retrieves a reference to the next child of the parent for the object. nodeName * String true Retrieves the name of a particular type of node. nodeType * Number true Retrieves the type of the requested node. nodeValue * String true Retrieves the value of a node. ownerDocument * Document true Retrieves the Document object associated with the node. parentNode * Node true Retrieves the parent object in the object hierarchy. prefix * String true Retrieves the namespace prefix specifief for the node. previousSibling * Node true Retrieves a reference to the previous child of the parent for the object. target String true Processing instruction target. Method Returns Description addEventListener * Void This method allows the registration of an event listener in the default group and, depending on the useCapture parameter, on the capture phase of the DOM event flow or its target and bubbling phases. Sytaxis: object.addEventListener(type, listener, useCapture) Arguments: Name Type O/R Description type String Required Specifies the Event.type associated with the event for which the user is registering. listener Function Required Function to be called when the event occurs. useCapture Boolean Required If true, user wishes to add the event listener for the capture phase only, if false - for target and bubbling phases. appendChild * Node Appends a child element to the object. Sytaxis: object.appendChild(node) Arguments: Name Type O/R Description node Node Required The node to add. canDispatch * Void Tests wether event of the specified namespace and type can be dispatched. Sytaxis: object.canDispatch(namespaceURI, type) Arguments: Name Type O/R Description namespaceURI String Required NamespaceURI of the event to be tested. type String Required Event type. cloneNode * Node Creates a copy of node and returns it. Sytaxis: object.cloneNode(deep) Arguments: Name Type O/R Description deep Boolean Required Indicates wether the childnodes are also to be cloned. compareDocumentPosition * Number Compares the reference node, i.e. the node on which this method is being called, with a node, i.e. the one passed as a parameter, with regard to their position in the document and according to the document order. Sytaxis: object.compareDocumentPosition(node) Arguments: Name Type O/R Description node Node Required The node to compare against the reference node. dispatchEvent * Boolean This method allows the dispatch of events into the implementation's event model. Return value indicates whether any of the listeners which handled the event called preventDefault method on Event object. Sytaxis: object.dispatchEvent(event) Arguments: Name Type O/R Description event Event Required The event to be dispatched. hasAttributes * Boolean Retrieves true if the node has any attributes. Sytaxis: object.hasAttributes() hasChildNodes * Boolean Returns a value that indicates whether the object has children. Sytaxis: object.hasChildNodes() insertBefore * Node Inserts a chlid element after the specifyed element to the object. Sytaxis: object.insertBefore(node, before) Arguments: Name Type O/R Description node Node Required The node to insert. before Node Required The reference node, i.e., the node before which the new node must be inserted. isDefaultNamespace * String This method checks if the specified namespaceURI is the default namespace or not. Sytaxis: object.isDefaultNamespace(namespaceURI) Arguments: Name Type O/R Description namespaceURI String Required The namespace URI to look for. lookupNamespaceURI * String Look up the namespace URI associated to the given prefix, starting from this node. Sytaxis: object.lookupNamespaceURI(prefix) Arguments: Name Type O/R Description prefix String Required The prefix to look for. If this parameter is null, the method will return the default namespace URI if any. lookupPrefix * String Look up the prefix associated to the given namespace URI, starting from this node. Sytaxis: object.lookupPrefix(namespaceURI) Arguments: Name Type O/R Description namespaceURI String Required The namespace URI to look for. normalize * Void Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form Sytaxis: object.normalize() removeChild * Node Removes a child node from the object. Sytaxis: object.removeChild(child) Arguments: Name Type O/R Description child Node Required The node being removed. removeEventListener * Void This method allows the removal of event listeners from the default group. Sytaxis: object.removeEventListener(type, listener, useCapture) Arguments: Name Type O/R Description type String Required Specifies the Event.type for which the user registered the event listener. listener Function Required Listener to be removed. useCapture Boolean Required Specifies whether the EventListener being removed was registered for the capture phase or not. replaceChild * Node Replaces the given child node by another node. Sytaxis: object.replaceChild(new, child) Arguments: Name Type O/R Description new Node Required The new node to put in the child list. child Node Required The node being replaced in the list. toXML * String Serializes Node to string. Sytaxis: object.toXML() Event B C Interface Description DOMNodeInserted * + - MutationEvent A node has been added as a child of another node or, in case of Attr nodes, has been added to an Element. DOMNodeInsertedIntoDocument * - - MutationEvent A node has been inserted into a document. DOMNodeRemoved * + - MutationEvent A node is being removed from its parent node or, in case of Attr nodes, removed from its ownerElement. DOMNodeRemovedFromDocument * - - MutationEvent A node is being removed from a document. Pseudo-class Description Constant Value Description
