Node Types

Documents, elements, attributes, and other aspects of an HTML or XML document has different node types.

There are 12 different node types, which may have children of various node types:

Node type Description Children
1 Element Represents an element Element, Text, Comment, ProcessingInstruction, CDATASection, EntityReference
2 Attr Represents an attribute Text, EntityReference
3 Text Represents textual content in an element or attribute None
4 CDATASection Represents a CDATA section in a document (text that will NOT be parsed by a parser) None
5 EntityReference Represents an entity reference Element, ProcessingInstruction, Comment, Text, CDATASection, EntityReference
6 Entity Represents an entity Element, ProcessingInstruction, Comment, Text, CDATASection, EntityReference
7 ProcessingInstruction Represents a processing instruction None
8 Comment Represents a comment None
9 Document Represents the entire document (the root-node of the DOM tree) Element, ProcessingInstruction, Comment, DocumentType
10 DocumentType Provides an interface to the entities defined for the document None
11 DocumentFragment Represents a "lightweight" Document object, which can hold a portion of a document Element, ProcessingInstruction, Comment, Text, CDATASection, EntityReference
12 Notation Represents a notation declared in the DTD None

Node Types - Return Values

Example

Get the node types of the <body> element's child nodes:

var c = document.body.childNodes;
var txt = "";
var i;
for (i = 0; i < c.length; i++) {
    txt = txt + c[i].nodeType + "<br>";
}

document.getElementById("demo").innerHTML = txt;

The result of txt will be:

3    // text node
1    // element node
3    // text node
1    // element node
3    // text node
1    // element node
3    // text node
8    // comment node
3    // text node
1    // element node
3    // text node
1    // element node
3    // text node
1    // element node
3    // text node

Example

Get the node name, node value and the node type of the <div> element's first child node:

<div id="myDIV">This is a div element.</div>

<script>
var x = document.getElementById("myDIV").firstChild;
var txt = "";
txt += "The node name: " + x.nodeName + "<br>";
txt += "The node value: " + x.nodeValue + "<br>";
txt += "The node type: " + x.nodeType;
</script>

The result of txt will be:

The node name: #text
The node value: This is a div element.
The node type: 3
