After you’ve read Chapter Two, this Part will provide the information you need to go deeper into XML. Chapters 15 through 20 can be read in order to learn the XML language and the key technologies that are used with it: XPath, XSLT, and Web services.
Chapters 21 and 22 will teach you both parts of the XML Schema standard: datatypes and the XML Schema definition language. We go into enough detail that you will be able to create practical schemas and understand those that are provided for your use.
Chapters 23 and 24 provide more advanced information about Web services and XPath.
