The XML explosion hardly needs any introduction-it's everywhere and there just seems to be no end to what can be done with XML. While writing to the W3C standards, and keeping up with the pace for corporate implementation, you, the programmer or web developer, will need a comprehensive guide to get you started and show you what XML and its related technologies can do. A thorough guide is imperative to success because you will need to know and understand the full scope of XML from day one in order to work with it successfully. With your time constraints and impossible project schedules, you need a comprehensive guide that fulfills your needs in one complete book. Inside XML is an anchor book that covers both the Microsoft and non-Microsoft approach to XML programming. It covers in detail the hot aspects of XML; such as, DTD's vs. XML Schemas, CSS, XSL, XSLT, Xlinks, Xpointers, XHTML, RDF, CDF, parsing XML in Perl and Java, and much more.
