From the Publisher: The first complete hands-on guide to programming with XPath XPath Essentials Web masters at large corporations need to import XML data from their companies data warehouses and display it with HTML on Web sites. XPath allows that data to be restructured. IT programmers need to build andor maintain business-to-business (B2B) applications for their companies to interact with a wide variety of clients and partners. While the clients and partners may all have the necessary data in XML format, they may not all be using the same naming conventions for the data. XPath exchanges the XML data without any of the companies having to change their systems. XPath Essentials offers Web masters and IT programmers a thorough source for XPath coverage. Offering many pertinent examples of how XPath technology operates, this book shows how XPath allows XML data to be restructured so that it can be transformed, displayed, and exchanged among companies that may not be using the same DTDs or schemas. Written by an internationally recognized XML expert with extensive writing and technical editing experience, XPath Essentials focuses exclusively on XPath. It delivers everything you need to know about this extraordinary program, including: Extensive examples and source code to illustrate the practical application of XPath and its framework, syntax, semantics, and use In-depth coverage that developers need to accomplish mission-critical tasks A casual, accessible tone and style geared toward professional developers who arent necessarily XML experts Appendices of resources and an XPath glossary
