XML DOM

What is XML DOM

DOM is an acronym stands for Document Object Model. It defines a standard way to access and manipulate documents. The Document Object Model (DOM) is a programming API for HTML and XML documents. It defines the logical structure of documents and the way a document is accessed and manipulated.

As a W3C specification, one important objective for the Document Object Model is to provide a standard programming interface that can be used in a wide variety of environments and applications. The Document Object Model can be used with any programming language.

XML DOM Example : Load XML File

Let's take an example to show how an XML document ("note.xml") is parsed into an XML DOM object.

This example parses an XML document (note.xml) into an XML DOM object and extracts information from it with JavaScript.

Let's see the XML file that contains message.

note.xml

Let's see the HTML file that extracts the data of XML document using DOM.

xmldom.html

Output:

XML DOM Example : Load XML String

This example parses an XML string into an XM DOM object and then extracts some information from it with a JavaScript.

Let's see the HTML file that extracts the data of XML string using DOM.
