Xpath expressions offer a flexible structure for navigating inside an XML document. While they are usually used in conjunction with XSLT style sheets to identify pieces of an XML document targeted for transformations, they can be effective in any application that needs to extract information from an XML document.

TAME (Tag-Activated Markup Enhancer) is a new programming language that is platform-independent, server-side, interpretive, and contains full integration with XML

There are times when the resource your Java application needs is available from a Web site. You can see it by pointing your browser to its URL. You just need to have your application access it. The java.net.HttpURLConnection class will help you do just that.

Taglibs provide a reusable framework for J2EE application development, but their key to success is availability. The more complete the tag libraries are, the more the need to write Java code directly inside the JSP page or via JavaBeans diminishes.

In the old days, when data was stored in plain text files, scripting languages were quite popular. With a lot of data now moving to XML, it becomes an interesting exercise to see how scripting languages have evolved to support XML-based data.

Check out the ability to compile XSLT. Learn about XSLTC and translets as well!

Comparing two files is easy with the right tool. What is the right tool for XML documents?

The recursive aspect of XSLT often leads to elegant and concise transformations. It is the ability to make exceptions during this recursion, however, which makes XSLT quite useful. This article illustrates the simple syntax needed to do branching during a

We begin a new column on useful Java classes by looking at Timer and TimerTask, which facilitate execution of code at a predetermined time or during specified time intervals.

Will data binding make XML irrelevant?

Jabber brings together real-time messaging and XML.
