XML DOM Node Types


The DOM presents a document as a hierarchy of node objects.


Node Types

The following table lists the different W3C node types, and which node types they may have as children:

Node TypeDescriptionChildren
DocumentRepresents the entire document (the root-node of the DOM tree)Element (max. one), ProcessingInstruction, Comment, DocumentType
DocumentFragmentRepresents a "lightweight" Document object, which can hold a portion of a documentElement, ProcessingInstruction, Comment, Text, CDATASection, EntityReference
DocumentTypeProvides an interface to the entities defined for the documentNone
ProcessingInstructionRepresents a processing instructionNone
EntityReferenceRepresents an entity referenceElement, ProcessingInstruction, Comment, Text, CDATASection, EntityReference
ElementRepresents an elementElement, Text, Comment, ProcessingInstruction, CDATASection, EntityReference
AttrRepresents an attributeText, EntityReference
TextRepresents textual content in an element or attributeNone
CDATASectionRepresents a CDATA section in a document (text that will NOT be parsed by a parser)None
CommentRepresents a commentNone
EntityRepresents an entityElement, ProcessingInstruction, Comment, Text, CDATASection, EntityReference
NotationRepresents a notation declared in the DTDNone


Node Types - Return Values

The following table lists what the nodeName and the nodeValue properties will return for each node type:
