Explains how to process XML with Java, build XML applications, and parse complicated documents. Written for experienced Java developers, the book focuses on the three major Java APIs that model XML: the simple API for XML (SAX), the document object model (DOM), and a Java native API (JDOM). The final two chapters introduce the XPath language for locating nodes in XML documents, and XSL transformations (XSLT) for describing how documents change formats.
