Remarks

The Node interface is the primary datatype for the entire Document Object Model. It represents a single node in the document tree. While all objects implementing the Node interface expose methods for dealing with children, not all objects implementing the Node interface may have children. For example, Text nodes may not have children, and adding children to such nodes results in a DOMException being raised.

The attributes nodeName, nodeValue and attributes 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 specific nodeType (e.g., nodeValue for an Element or attributes for a Comment ), this returns null. Note that the specialized interfaces may contain additional and more convenient mechanisms to get and set the relevant information.

The values of nodeName, nodeValue, and attributes vary according to the node type as follows: <table border='1' cellpadding='3'> <tr> <th>Interface</th> <th>nodeName</th> <th>nodeValue</th> <th>attributes</th> </tr> <tr> <td valign='top' rowspan='1' colspan='1'> Attr</td> <td valign='top' rowspan='1' colspan='1'>same as Attr.name</td> <td valign='top' rowspan='1' colspan='1'>same as Attr.value</td> <td valign='top' rowspan='1' colspan='1'>null</td> </tr> <tr> <td valign='top' rowspan='1' colspan='1'>CDATASection</td> <td valign='top' rowspan='1' colspan='1'> "#cdata-section"</td> <td valign='top' rowspan='1' colspan='1'>same as CharacterData.data, the content of the CDATA Section</td> <td valign='top' rowspan='1' colspan='1'>null</td> </tr> <tr> <td valign='top' rowspan='1' colspan='1'>Comment</td> <td valign='top' rowspan='1' colspan='1'> "#comment"</td> <td valign='top' rowspan='1' colspan='1'>same as CharacterData.data, the content of the comment</td> <td valign='top' rowspan='1' colspan='1'>null</td> </tr> <tr> <td valign='top' rowspan='1' colspan='1'>Document</td> <td valign='top' rowspan='1' colspan='1'> "#document"</td> <td valign='top' rowspan='1' colspan='1'>null</td> <td valign='top' rowspan='1' colspan='1'>null</td> </tr> <tr> <td valign='top' rowspan='1' colspan='1'> DocumentFragment</td> <td valign='top' rowspan='1' colspan='1'>"#document-fragment"</td> <td valign='top' rowspan='1' colspan='1'> null</td> <td valign='top' rowspan='1' colspan='1'>null</td> </tr> <tr> <td valign='top' rowspan='1' colspan='1'>DocumentType</td> <td valign='top' rowspan='1' colspan='1'>same as DocumentType.name</td> <td valign='top' rowspan='1' colspan='1'>null</td> <td valign='top' rowspan='1' colspan='1'>null</td> </tr> <tr> <td valign='top' rowspan='1' colspan='1'> Element</td> <td valign='top' rowspan='1' colspan='1'>same as Element.tagName</td> <td valign='top' rowspan='1' colspan='1'>null</td> <td valign='top' rowspan='1' colspan='1'> NamedNodeMap</td> </tr> <tr> <td valign='top' rowspan='1' colspan='1'>Entity</td> <td valign='top' rowspan='1' colspan='1'>entity name</td> <td valign='top' rowspan='1' colspan='1'>null</td> <td valign='top' rowspan='1' colspan='1'> null</td> </tr> <tr> <td valign='top' rowspan='1' colspan='1'>EntityReference</td> <td valign='top' rowspan='1' colspan='1'>name of entity referenced</td> <td valign='top' rowspan='1' colspan='1'> null</td> <td valign='top' rowspan='1' colspan='1'>null</td> </tr> <tr> <td valign='top' rowspan='1' colspan='1'>Notation</td> <td valign='top' rowspan='1' colspan='1'>notation name</td> <td valign='top' rowspan='1' colspan='1'> null</td> <td valign='top' rowspan='1' colspan='1'>null</td> </tr> <tr> <td valign='top' rowspan='1' colspan='1'>ProcessingInstruction</td> <td valign='top' rowspan='1' colspan='1'>same as ProcessingInstruction.target</td> <td valign='top' rowspan='1' colspan='1'>same as ProcessingInstruction.data</td> <td valign='top' rowspan='1' colspan='1'>null</td> </tr> <tr> <td valign='top' rowspan='1' colspan='1'>Text</td> <td valign='top' rowspan='1' colspan='1'> "#text"</td> <td valign='top' rowspan='1' colspan='1'>same as CharacterData.data, the content of the text node</td> <td valign='top' rowspan='1' colspan='1'>null</td> </tr> </table>
