Following this, the book delves into CSS Style Sheets, XML Schema Basics, XSL and XSLT, SOAP, DOM Programming Interface, SAX, XPath, XLink, XQuery, XPointer, XForms, XSL-FO, and using XML with Databases. The final chapters cover Web Services, providing a comprehensive understanding of how XML integrates into various applications.
Mastering these standards and technologies is crucial for developers working with XML. This book transitions readers from basic XML syntax to advanced applications, blending theoretical concepts with practical examples. It is an essential resource for developers looking to leverage XML in their projects.
