HTML DOM Questions And Answers

1⟩ Explain DOM and how does it relate to XML?

The Document Object Model (DOM) is an interface

specification maintained by the W3C DOM Workgroup that

defines an application independent mechanism to access,

parse, or update XML data. In simple terms it is a

hierarchical model that allows developers to manipulate XML

documents easily Any developer that has worked extensively

with XML should be able to discuss the concept and use of

DOM objects freely. Additionally, it is not unreasonable to

expect advanced candidates to thoroughly understand its

internal workings and be able to explain how DOM differs

from an event-based interface like SAX.

2⟩ Explain multi-tagging?

Multi-tagging is a technique used by the DOM browser extension to identify a web page UI object. Whenever possible, DOM extension inserts more than one tag into the object identifier in following format:

Browser.BrowserChild(page_title).html_class(caption_tag|window_tag)

1. Caption_tag is the caption of the HTML element.

2. #index_tag is the index of this HTML element, counting from the beginning of this page of the same class of HTML elements.

3⟩ What is difference between DOM and SAX? What would we use if an option is given?

DOM parses an XML document and returns an instance of org.w3c.dom.Document. This document object's tree must then

be "walked" in order to process the different elements. DOM parses the ENTIRE Document into memory, and then makes it

available to you. The size of the Document you can parse is limited to the memory available.

4⟩ What is the DOM?

The DOM is a W3C (World Wide Web Consortium) standard.

The DOM defines a standard for accessing documents like HTML and XML:

"The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."

The DOM is separated into 3 different parts / levels:

* Core DOM - standard model for any structured document

* XML DOM - standard model for XML documents

* HTML DOM - standard model for HTML documents

The DOM defines the objects and properties of all document elements, and the methods (interface) to access them.
