DOM Create Nodes

This lesson is part of XML · All levels

Summary

New nodes are created with createElement for elements, createAttribute for attributes, and createTextNode for text. The output of the creation has not been connected to the tree so it must be added with an appendChild or insertBefore. This pattern allows you to build dynamic parts of a document according to the data.

Key points

CreateElement creates an empty element that is not yet installed
CreateAttribute sets up attributes with a specific name
CreateTextNode wrapped text as a text node
New nodes have to be added to the tree to make it appear.
The formation of nodes supports dynamically growing documents
