This book is primarily a practical reference book for professional XSLT developers. This does not assume prior knowledge of the language, and many developers have used it as their first introduction to XSLT, but is not structured as a tutorial, and there are other books on XSLT that provide a soft approach for beginners. This book is suitable both for XSLT 1.0 users upgrading to XSLT 2.0, and for newcomers to XSLT. This book aims to tell you everything you need to know about the XSLT 2.0 language. However, there is an attachment of Saxon (the author of its own implementation of XSLT 2.0?), On the implementation of the Altova XSLT 2.0, and on Java and Microsoft APIs for controlling the XSLT transformation, which will no doubt be upgraded to handle XSLT 2.0 as well as 1.0. A third XSLT 2.0 processor, Gestalt, was released shortly before the book went to press, too late to describe it in detail. But the experience of XSLT 1.0 is that there has been a very high level of interoperability between different XSLT processors, and if you can use one of them, then you can use them all. In previous editions we split XSLT 2.0 and XPath 2.0 into separate volumes. However, many buy the book XSLT 2.0 and XPath unaccompanied left confused as a result, so this time, the material back together. XPath reference information in the chapters independent, so it still must be accessed when you use XPath in contexts other than XSLT. This book contains twenty-eight chapters and attachments (the latter is the glossary) is divided into four sections. Chapter 1: XSLT in Context: This chapter explains how XSLT fits into the big picture: how language came into existence and how to sit with other technologies. Chapter 2: The XSLT Processing Model: This is the XSLT processor architecture: input, output, and model data. Chapter 3: Stylesheet Structure: XSLT stylesheet development of writing, and this chapter took the bird like? Eye view of what looks to the stylesheet. Chapter 4: stylesheet and Schemas: A key innovation in XSLT 2.0 stylesheet is that you can take advantage of knowledge about the structure of your input and output documents, provided in the form of XML Schema. Chapter 5: System Type: XPath 2.0 and XSLT 2.0 offer strong typing as an alternative approach than 1.0 weakly typed language. Part II: XSLT and XPath Reference: This section of the book contains reference material, organized in the hope that you can easily find what you need when you need it. Chapter 6: XSLT Elements: This monster chapter lists all XSLT elements that you can use in the stylesheet, in alphabetical order, giving detailed rules for the syntax and semantics of each element, advice on the use of, and examples. Chapter 7: XPath Fundamentals: This chapter explains the basics of XPath: the low-level structures such as literals, variables, and function calls. This also explains the context rules, which describe how the evaluation of XPath expressions depends on the XSLT processing context in which they appear. Chapter 8: XPath: Operators on the Product: XPath offers a variety of normal operators to perform arithmetic, boolean comparisons, and the like. Chapter 9: XPath: Path Expressions: Path expressions are what makes XPath particular, they allow you to navigate around the structure of XML documents. Chapter 10: XPath: Sequence Expressions: Unlike XPath 1.0, in version 2.0 all values are sequences (singletons that only a special case). Chapter 11:: Expressions: XPath Type type system described in Chapter 5, this chapter explains the operations that you can use to take advantage of a kind. Chapter 12: XSLT Patterns: XPath of the back section to that subject? It's specific to XSLT. Chapter 13: Library Function: XPath 2.0, including library functions that can be called from XPath expressions, XSLT 2.0 extends this with some additional functions that are available only when XPath is used in XSLT. Chapter 14: Regular Expressions: text processing is an area where XSLT 2.0 and XPath 2.0 is much more powerful than version 1.0, and this is largely through the use of construction that exploit regular expressions. Chapter 15: Serialization: Serialization in XSLT means the ability to generate a textual XML document from the stylesheet tree? S manipulated by. This is not it? Part t XSLT processing proper, so that (after the W3C? S lead) it s separated? Into its own chapter. Part III: Exploitation: The final part of this book advice and guidance on how to take advantage of XSLT to write real applications.
