Section 1 – Introduction Tutorial – XML Programming in Java 2 Section 1 – Introduction About this tutorial Our previous tutorial discussed the basics of XML and demonstrated its potential to revolutionize the Web. In this tutorial, we’ll discuss how to use an XML parser to: • Process an XML document • Create an XML document • Manipulate an XML document We’ll also talk about some useful, lesser-known features of XML parsers. Best of all, every tool discussed here is freely available at IBM’s alphaWorks site (www.alphaworks.ibm.com) and other places on the Web. What’s not here There are several important programming topics not discussed here: • Using visual tools to build XML applications • Transforming an XML document from one vocabulary to another • Creating interfaces for end users or other processes, and creating interfaces to back-end data stores All of these topics are important when you’re building an XML application. We’re working on new tutorials that will give these subjects their due, so watch this space! XML application architecture An XML application is typically built around an XML parser. It has an interface to its users, and an interface to some sort of back-end data store. This tutorial focuses on writing Java code that uses an XML parser to manipulate XML documents.
