DOM and its impact on web development techniques - Essay Example

Lecturer Impact of DOM on Web Development Techniques Document Object Model (DOM) entails a language independent and also cross platform convention that represents and interacts with objects in XML, HTML, and XHTML documents. Objects in DOM tree are addressed and manipulated using methods on objects. Public interface of the DOM is indicated in the Application Programming Interface (API) (Guisset, 2009). The World Wide Web Consortium (W3C) promotes open Standards in the World Wide Web. W3C has continuously worked on the standardized DOM.

DOM level 1 is the initial DOM standard recommended in 1998 by W3C. The DOM level 1 provided complete model for the XML and HTML documents, including methods of reviewing portions of the documents. DOM level 2 was introduced in 2000. The level has event model and supports XML namespaces and CSS. DOM level 3 is the current DOM specifications release published in 2004. It has added additional features for XPath, Keyboard event handling, and serialization interface for documents like XML. DOM level 4 is currently in the process of being developed.

As at 2005, majority of the W3C DOM were effectively supported through common browsers like Microsoft Internet Explorer Version 6, Mozilla, Firefox, and Opera (Koch, 2001). To produce documents like HTML page, majority of the web browsers internal DOM model. The nodes of documents are arranged in DOM tree structure, with the document object being the topmost node. When HTML page is opened in browsers; the HTML is downloaded into the local memory, and automatically displays the page on the screen (Guisset, 2009).

DOM supports all navigation directions and allows arbitrary modifications; hence implementation buffers documents that are read. BibliographyGuisset, F. (2009).What does each DOM Level bring? Mozilla Developer Koch, P. (2001). The Document Object Model: an Introduction. Digital Web Magazine.
