XML Programming With JavaScript
Duration
Two days
Summary
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 the basic concepts of XML, attaching XML files to HTML files, and writing JavaScript to parse and present the XML data in the browser.
Audience
Webmasters and others interested in taking advantage of XML's create-one, use-many-times methodologies.
Pre-requisites
The participants have a general knowledge of HTML and JavaScript preferred. Students with programming experience but no experience in JavaScript will still be able to write basic pages and XML extracts.
