Node

Node Types

A node type can be obtained with getNodeType() call, and it is one of the following:

Node Name, Value and Attributes

Interface	nodeName	nodeValue	attributes
Attr	same as Attr.name	same as Attr.value	null
CDATASection	"#cdata-section"	same as CharacterData.data, the content of the CDATA Section	null
Comment	"#comment"	same as CharacterData.data, the content of the comment	null
Document	"#document"	null	null
DocumentFragment	"#document-fragment"	null	null
DocumentType	same as DocumentType.name	null	null
Element	same as Element.tagName	null	NamedNodeMap
Entity	entity name	null	null
EntityReference	name of entity referenced	null	null
Notation	notation name	null	null
ProcessingInstruction	same as ProcessingInstruction.target	same as ProcessingInstruction.data	null
Text	"#text"	same as CharacterData.data, the content of the text node	null

Node's Text Content

To get the text a node contains, you need to look through the list of child nodes, ignoring entries that are of no concern and accumulating the text you find in TEXT nodes, CDATA nodes, and EntityRef nodes.
