Element	1	An element (for example, <item> ).
Attribute	2	An attribute (for example, id='123' ).
Text	3	The text content of a node. A Text node cannot have any child nodes. It can appear as the child node of the Attribute, DocumentFragment, Element, and EntityReference nodes.
CDATA	4	A CDATA section (for example, <![CDATA[my escaped text]]> ).
EntityReference	5	A reference to an entity (for example, &num; ).
Entity	6	An entity declaration (for example, <!ENTITY...> ).
ProcessingInstruction	7	A processing instruction (for example, <?pi test?> ).
Comment	8	A comment (for example, <!-- my comment --> ).
Document	9	A document object that, as the root of the document tree, provides access to the entire XML document.
DocumentType	10	The document type declaration, indicated by the following tag (for example, <!DOCTYPE...> ).
DocumentFragment	11	A document fragment.
Notation	12	A notation in the document type declaration (for example, <!NOTATION...> ).
Whitespace	13	White space between markup.
SignificantWhitespace	14	White space between markup in a mixed content model or white space within the xml:space="preserve" scope.
EndElement	15	An end element tag (for example, </item> ).
EndEntity	16	Returned when XmlReader gets to the end of the entity replacement as a result of a call to ResolveEntity().
XmlDeclaration	17	The XML declaration (for example, <?xml version='1.0'?> ). The XmlDeclaration node must be the first node in the document. It cannot have children. It is a child of the Document node. It can have attributes that provide version and encoding information.
