If you're a developer working with XML, you know there's a lot to know about XML, and the XML space is evolving almost moment by moment. But you don't need to commit every XML syntax, API, or XSLT transformation to memory; you only need to know where to find it. And if it's a detail that has to do with XML or its companion standards, you'll find it--clear, concise, useful, and well-organized--in the updated third edition of XML in a Nutshell. With XML in a Nutshell beside your keyboard, you'll be able to:

with: Joe Marini

XML, or Extensible Markup Language, was designed to make information sharing and data interpretation easier, but it only works if you know how to work it. In XML Essential Training, veteran engineer and instructor Joe Marini takes you through the basic rules of XML, discusses suggested tools,

Pulling the Pieces Together

An important application of XML is the interchange of electronic data (EDI) between multiple data sources on the Web. As XML data proliferates on the Web, applications will need to integrate and aggregate data from multiple source and clean and transform data to facilitate exchange. Data extraction, conversion, transformation, and integration are all well-understood database problems, and their solutions rely on a query language. We present a query language for XML, called XML-QL, which we argue is suitable for performing the above tasks.

SVG - Scalable Vector Graphics
SVG is an example of an XML application. Using SVG we can create images made up of lines, shapes and text.
DTD - Document Type Definition (more DTD)
A DTD describes an XML application. An XML documents may be validated against a DTD. The DTD specifies the elements that may be included, how they may be nested and what attributes each element may have.
