XML Programming with Javascript

XML Programming with Javascript

Audience

Webmasters and others interested in taking advantage of XML's create-one, use-many-times methodologies.

Prerequisites

Participants should have a general knowledge of HTML and JavaScript. Students with programming experience but no experience in JavaScript will still be able to write basic pages and XML extracts.

Duration

2 days.

Course Objectives

XML data can be 'attached' to HTML documents when they are sent to the browser, thus, allowing you to use JavaScript to manipulate the data and present the user with a variety of different representations of their data without any additional server-side processing.

In this course, students are introduced to the basic concepts of XML, attaching XML files to HTML files, and writing JavaScript to parse and present the XML data in the browser.
