XML DOM Create Nodes – Iampsp Blog

Create a New Element Node

The createElement() method creates a new element node:

Example

newElement = xmlDoc.createElement("edition");

xmlDoc.getElementsByTagName("book")[0].appendChild(newElement);

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);

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");

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);

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);

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);
