Remarks

The DOMNodeType enumeration defines the following valid values for the nodeType property.

NODE_ELEMENT (1)

The node represents an element. An element node can have the following child node types: Element, Text, Comment, ProcessingInstruction, CDATASection, and EntityReference. An element node can be the child of the Document, DocumentFragment, EntityReference, and Element nodes.

NODE_ATTRIBUTE (2)

The node represents an attribute of an element. An attribute node can have the following child node types: Text and EntityReference. The attribute does not appear as the child node of any other node type; note that it is not considered a child node of an element.

NODE_TEXT (3)

The node represents the text content of a tag. A text node cannot have any child nodes. The text node can appear as the child node of the Attribute, DocumentFragment, Element, and EntityReference nodes.

NODE_CDATA_SECTION (4)

The node represents a CDATA section in the XML source. CDATA sections are used to escape blocks of text that would otherwise be recognized as markup. A CDATA section node cannot have any child nodes. The CDATA section node can appear as the child of the DocumentFragment, EntityReference, and Element nodes.

NODE_ENTITY_REFERENCE (5)

The node represents a reference to an entity in the XML document. This applies to all entities, including character entity references. An entity reference node can have the following child node types: Element, ProcessingInstruction, Comment, Text, CDATASection, and EntityReference. The entity reference node can appear as the child of the Attribute, DocumentFragment, Element, and EntityReference nodes.

NODE_ENTITY (6)

The node represents an expanded entity. An entity node can have child nodes that represent the expanded entity (for example, Text and EntityReference nodes). The entity node can appear as the child of the DocumentType node.

NODE_PROCESSING_INSTRUCTION (7)

The node represents a processing instruction (PI) from the XML document. A PI node cannot have any child nodes. The PI node can appear as the child of the Document, DocumentFragment, Element, and EntityReference nodes.

NODE_COMMENT (8)

The node represents a comment in the XML document. A comment node cannot have any child nodes. The comment node can appear as the child of the Document, DocumentFragment, Element, and EntityReference nodes.

NODE_DOCUMENT (9)

The node represents a document object, which, as the root of the document tree, provides access to the entire XML document. It is created using the ProgID "Microsoft.XMLDOM", or through a data island using <XML> or <SCRIPT LANGUAGE=XML>. The document node can have the following child node types: Element (maximum of one), ProcessingInstruction, Comment, and DocumentType. The document node cannot appear as the child of any node types.

NODE_DOCUMENT_TYPE (10)

The node represents the document type declaration, indicated by the <!DOCTYPE > tag. The document type node can have the following child node types: Notation and Entity. The document type node can appear as the child of the Document node.

NODE_DOCUMENT_FRAGMENT (11)

The node represents a document fragment. The document fragment node associates a node or subtree with a document without actually being contained within the document. The document fragment node can have the following child node types: Element, ProcessingInstruction, Comment, Text, CDATASection, and EntityReference. The DocumentFragment node cannot appear as the child of any node types.

NODE_NOTATION (12)

The node represents a notation in the document type declaration. The notation node cannot have any child nodes. The notation node can appear as the child of the DocumentType node.
