- Attr: a pair of properties and values
- Text: contents between a tag in XML(nodes with only text inside).
- CDataSection:
<![CDATA[]]>, can only conclude nodes of text. - Entity: define an entity like

. - ProcessingInstruction: stand for a PI, like
<?target data?>. - Comment: XML comment.

Properties or Methods of nodes:
- NodeList: a list of child nodes
- NamedNodeMap: a map of paired keys with attributes and values
| Properties/Methods | Types/Returned types | Descriptions |
|---|---|---|
| nodeName | String | the name of the node |
| nodeValue | String | the value of the node |
| nodeType | Number | the type of the node |
| ownerDocument | Document | the owner document of the node |
| firstChild | Node | the first node in the list - childNodes |
| lastChild | Node | the last node in the list - childNodes |
| childNodes | NodeList | a list of all the child nodes |
| previousSibling | Node | the previous brother node |
| nextSibling | Node | the next brother node |
| attributes | NamedNodeMap | conclude the Attr which can represent the properties of this node |
| hasChildNodes() | Boolean | return true when there is a child node |
| appendChild(Node) | Node | add a node into the list - childNodes |
| removeChild(Node) | Node | remove a node from the list - childNodes |
| replaceChild(newnode, oldnode) | Node | replace an oldnode from the list - childNodes with the newnode |
