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. In
the beautiful picture on the left, this tutorial is
focused on the middle box.
