Part IV: At a Glance

Programming and XML

Part IV looks at how to use programming to get the most out of XML. Programming has a great deal to offer the XML author, and you'll start this part by taking a look at working with JavaScript in Web pages.

By using JavaScript, you can load XML documents and parse them, searching through their data for an item. You're going to see how to do that, as well as how to validate XML documents that use either DTDs or XML schemas by using JavaScript.

You'll also take a look at how to use XML with Java in this part. Versions 1.4 and later of Java have a great deal of support for XML built in. You're going to take advantage of that support in both the XML Document Object Model (DOM) and the Simple API for XML (SAX).

In this part you're also going to take a look at how to work with the Simple Object Access Protocol (SOAP). SOAP is an XML-based protocol that lets applications communicate on the Internet, and you'll take a look at working with SOAP both with Java and .NET programming. (If you're a .NET programmer, you should take a look at Day 21, which is dedicated to .NET XML programming.)
