XSLT is an essential tool for converting XML into other kinds of documents: HTML, PDF file, and many others. It's a critical technology for XML-based platforms such as Microsoft .NET, Sun Microsystems' Sun One, as well as for most web browsers and authoring tools. As useful as XSLT is, however, most people have a difficult time getting used to its peculiar characteristics. The ability to use advanced techniques depends on a clear and exact understanding of how XSLT templates work and interact.The XSLT 1.0 Pocket Reference from O'Reilly wants to make sure you achieve that level of understanding. With its concise approach, this handy pocket guide quickly gets you up to speed on XSLT 1.0 so you can covert XML like a seasoned pro. In addition to covering the basics of stylesheet structure, it also explains how to:use template rulescreate a result treeapply conditional processingtransform multiple source documentsemploy number formattingThanks to their convenient, quick-reference format, O'Reilly's Pocket References spare you from having to hunt through larger books for answers.

Globe-trotting travelers have long resorted to handy, pocket-size dictionaries as an aid to communicating across the language barrier. Dan Pilone's UML 2.0 Pocket Reference is just such an aid for on-the-go developers who need to converse in the Unified Modeling Language (UML). Use this book to decipher the many UML diagrams you'll encounter on the path to delivering a modern software system.Updated to cover the very latest in UML, you'll find coverage of the following UML 2.0 diagram types:Class diagramsComponent diagrams*Sequence diagrams*Communication diagrams*Timing diagrams*Interaction Overview diagrams*Package diagrams*Deployment diagrams*Use case diagramsComposite structure diagrams*Activity diagrams*Statechart diagrams** New or expanded coverage in this editionAlso new in this edition is coverage of UML's Object Constraint Language (OCL). Using OCL, you can specify more narrowly the functionality described in a given diagram by recording limits that are the result of business rules and other factors.The UML 2.0 Pocket Reference travels well to meetings and fits nicely into your laptop bag. It's near impossible to memorize all aspects of UML, and with this book along, you won't have to.

The STL Pocket Reference describes the functions, classes, and templates in that part of the C++ standard library often referred to as the Standard Template Library (STL). The STL encompasses containers, iterators, algorithms, and function objects, which collectively represent one of the most important and widely used subsets of standard library functionality.The C++ standard library, even the subset known as the STL, is vast. It's next to impossible to work with the STL without some sort of reference at your side to remind you of template parameters, function invocations, return types--indeed, the entire myriad of details you need to know in order to use the STL effectively and get work done. You need a memory-aid.Books that cover the standard library and the STL tend to be quite heavy and large, describing each aspect of the STL in detail. Such books are great when you're not familiar with the library, but get in the way when you simply need to remind yourself of a function name, or the order in which you pass arguments to a function. Programmers familiar with the STL need a small, lightweight memory-aid. That's what the STL Pocket Reference is. It's small, lightweight, and chock-full of information that you can take in at a glance, so you can get on with your work.

Support for regular expressions in SQL and PL/SQL is one of the most exciting features of Oracle Database 10G.

Few .NET developers have the luxury of unlimited code testing once their application is complete, and rushing through the testing process is both problematic and stressful. The open source NUnit framework provides an excellent and efficient way to test and improve .NET code as it's written, saving hundreds of QA hours and headaches.NUnit is one of the most mature and widely-used .NET open source projects even Microsoft uses it internally. NUnit is a unit-testing framework for all .Net languages. Written entirely in C#, NUnit takes advantage of many .NET language features, such as custom attributes and other reflection related capabilities. It automates unit testing and reduces the effort required to frequently test code while developing it. NUint is invaluable for .NET developers in test-driven development under agile methodologies such as Extreme Programming (XP) as well as for developers who use for unit testing for software quality assurance. Unfortunately, some of those valuable hours saved by using NUnit can be wasted trying to master this powerful but under-documented frameworkProof that good things come in small packages, the NUnit Pocket Reference is a complete reference to NUnit, filling in the blanks left by the existing documentation and online discussion. It offers developers everything they need to know to install, configure, and use NUnit; the NUnit user interface; and a reference to the NUnit framework classes in a slim but well-organized package. This handy little book even offers practical, real world NUnit examples. And with the NUnit Pocket Reference, IT managers will know to expect when they implement unit testing in their projects. It is the only book you'll need on this popular and practical new open source framework.

The HyperText Transfer Protocol, or HTTP, is the backbone of the World Wide Web. HTTP is the language that each web browser (or other web client) uses to communicate with servers around the world.
