Create an attribute node using createAttribute
This example uses createAttribute() to create a new attribute node, and setAttributeNode() to insert it to an element.

Create an attribute node using setAttribute
This example uses setAttribute() to create a new attribute for an element.

Create a text node

Create a New Element Node
The createElement() method creates a new element node:

Example
newElement = xmlDoc.createElement("edition");

xmlDoc.getElementsByTagName("book")[0].appendChild(newElement);
»
Example explained:

Suppose "books.xml" is loaded into xmlDoc
Create a new element node <edition>
Append the element node to the first <book> element
Loop through and add an element to all <book> elements: Try it yourself
Create a New Attribute Node
The createAttribute() is used to create a new attribute node:

Example
newAtt = xmlDoc.createAttribute("edition");
newAtt.nodeValue = "first";

xmlDoc.getElementsByTagName("title")[0].setAttributeNode(newAtt);
»
Example explained:

Suppose "books.xml" is loaded into xmlDoc
Create a new attribute node "edition"
Set the value of the attribute node to "first"
Add the new attribute node to the first <title> element
Loop through all <title> elements and add a new attribute node: Try it yourself

If the attribute already exists, it is replaced by the new one.

Create an Attribute Using setAttribute()
Since the setAttribute() method creates a new attribute if the attribute does not exist, it can be used to create a new attribute.

Example
xmlDoc.getElementsByTagName('book')[0].setAttribute("edition","first");
»
Example explained:

Suppose "books.xml" is loaded into xmlDoc
Set the attribute "edition" value to "first" for the first <book> element
Loop through all <title> elements and add a new attribute: Try it yourself

Create a Text Node
The createTextNode() method creates a new text node:

Example
newEle = xmlDoc.createElement("edition");
newText = xmlDoc.createTextNode("first");
newEle.appendChild(newText);

xmlDoc.getElementsByTagName("book")[0].appendChild(newEle);
»
Example explained:

Suppose "books.xml" is loaded into xmlDoc
Create a new element node <edition>
Create a new text node with the text "first"
Append the new text node to the element node
Append the new element node to the first <book> element
Add an element node, with a text node, to all <book> elements: Try it yourself

Create a CDATA Section Node
The createCDATASection() method creates a new CDATA section node.

Example
newCDATA = xmlDoc.createCDATASection("Special Offer & Book Sale");

xmlDoc.getElementsByTagName("book")[0].appendChild(newCDATA);
»
Example explained:

Suppose "books.xml" is loaded into xmlDoc
Create a new CDATA section node
Append the new CDATA node to the first <book> element
Loop through, and add a CDATA section, to all <book> elements: Try it yourself
Create a Comment Node
The createComment() method creates a new comment node.

Example
newComment = xmlDoc.createComment("Revised March 2015");

xmlDoc.getElementsByTagName("book")[0].appendChild(newComment);
»
Example explained:

Suppose "books.xml" is loaded into xmlDoc using
Create a new comment node
