Ajax Tradeoffs: The Many Flavors of XML

Ajax stands for Asynchronous JavaScript and XML and the idea is that with modern Web browsers you can, with acceptable reliability, keep a channel open to the server to pass data back and forth as your Web application is used. This contrasts with standard Web techniques that follow links, causing the entire page to load anew. Many aspects of Ajax-based development require design different decisions than traditional Web pages: How to manage the back button, how to display updated data, how often to send updates, and more. The focus for now will be on just one group of related aspects: what format should the data exchange take?

jQuery and XML Revisited

In releasing jQuery v.1.2, a decision was made by the development team to drop XPath support from the core. Instead, an officially released XPath jQuery plugin is now available, which provides deprecated functionality. Although initially disappointed by this decision, I was happy to discover that alternative methods for obtaining data from an XML file are still available without the plugin.
