Day 16. Using Java and .NET: DOM

Today, you're going to use Java to work with XML. Yesterday you saw how to work with XML and JavaScript, and today you're going to take the next step and create standalone programs using Java. Today you'll use the built-in Java support for the W3C DOM methods described yesterday. Here's an overview of today's topics:

  • Loading XML documents into a Java application
  • Parsing XML documents by using Java
  • Searching a document for a particular element
  • Navigating through an XML document by using Java
  • Creating graphical XML browsers by using Java
  • Modifying the XML in a document by using Java

Note that we must use Java version 1.4 or later if you want to take advantage of Java's integrated XML support for the W3C DOM, and you'll be using Java 1.4 today. There's all kinds of XML support built into Java 1.4 (with earlier versions, you have to use third-party packages), and you're going to jump right in by seeing how to read in an XML document and extract all the data from it.
