Editing Node (computer science) (section)

=== Node type ===
Different types of nodes in a tree are represented by specific interfaces. In other words, the node type is defined by how it communicates with other nodes. Each node has a node type property, which specifies the type of node, such as sibling or leaf.
For example, if the node type property is the constant properties for a node, this property specifies the type of the node. So if a node type property is the constant node ELEMENT_NODE, one can know that this node object is an object Element. This object uses the Element interface to define all the methods and properties of that particular node.

Different W3C [[World Wide Web Consortium]] node types and descriptions:
*'''Document''' represents the entire document (the root-node of the DOM tree) 	
*'''DocumentFragment''' represents a "lightweight" Document object, which can hold a portion of a document
*'''DocumentType''' provides an interface to the entities defined for the document
*'''ProcessingInstruction''' represents a processing instruction
*'''EntityReference''' represents an entity reference
*'''Element''' 	represents an element
*'''Attr''' represents an attribute
*'''Text''' represents textual content in an element or attribute
*'''CDATASection''' represents a [[CDATA]] section in a document (text that will NOT be parsed by a parser)
*'''Comment''' represents a comment
*'''Entity''' represents an entity
*'''Notation''' represents a notation declared in the DTD
