The example below uses the XML file books.xml.
Function loadXMLDoc(), located in external JavaScript, is used to load XML files.

Display the nodeName and nodeType of all elements

Display the nodeName and nodeValue of all elements

The following table lists the different W3C node types, each node type may contain subclasses:

##EntityRepresents an entityElement, ProcessingInstruction, Comment, Text, CDATASection, EntityReferenceNotationDefine a symbol declared in the DTDNone

Node type - return value

The following table lists the node name (nodeName) and node value (nodeValue) returned by each node type (nodetype):

DocumentType	Provides an interface for entities defined in documents	None
