XML DOM Create Nodes


Create a New Element Node

The createElement() method creates a new element node:

Example

newElement = xmlDoc.createElement("edition");

xmlDoc.getElementsByTagName("book")[0].appendChild(newElement);
Try it Yourself »

Example explained:

  1. Suppose books.xml is loaded into xmlDoc
  2. Create a new element node <edition>
  3. 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);
Try it Yourself »

Example explained:

  1. Suppose books.xml is loaded into xmlDoc
  2. Create a new attribute node "edition"
  3. Set the value of the attribute node to "first"
  4. 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");
Try it Yourself »

Example explained:

  1. Suppose books.xml is loaded into xmlDoc
  2. 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);
Try it Yourself »

Example explained:

  1. Suppose books.xml is loaded into xmlDoc
  2. Create a new element node <edition>
  3. Create a new text node with the text "first"
  4. Append the new text node to the element node
  5. 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);
Try it Yourself »

Example explained:

  1. Suppose books.xml is loaded into xmlDoc
  2. Create a new CDATA section node
  3. 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);
Try it Yourself »

Example explained:

  1. Suppose books.xml is loaded into xmlDoc using
  2. Create a new comment node
  3. Append the new comment node to the first <book> element

Loop through, and add a comment node, to all <book> elements: Try it yourself
