types are defined in a namespace maintained on the W3C organization web site. An Internet-style URL identifies the source file for an XML namespace. If an XML Schema declaration incorporates definitions from more than one XML namespace, the potential for name conflict exists. The same name could easily have been chosen by the developers of two different namespaces to represent two quite different XML structures or data types. To remove the potential ambiguity, XML data types and structure definitions can be specified using qualified names, using a technique that closely parallels the use of qualified column names in SQL. Each namespace that is identified in a schema header can be assigned a prefix name, which is then used to qualify references to items within that namespace. For clarity, the prefix names have been omitted from the schema examples in this chapter. Here is a more typical schema header and excerpt from a schema body that uses prefix names and qualification to reference the main XML Schema namespace (maintained by W3C) and a corporate namespace:

In this example, the corporate XML namespace is identified by the prefix corp and the main XML Schema namespace by the prefix xsd. All of the data type references are qualified by one of these prefixes, and as a result, they are unambiguous. Because qualified references can become quite cumbersome, it s also possible to specify default namespaces that minimize the need for prefixes. The complete XML Schema naming system is quite a bit more sophisticated than the capabilities outlined here, but the capabilities are clearly directed toward supporting the creation of very complex document type specifications by large groups of people. As with DTDs, the power of XML Schema is that it allows you to specify well-defined document types against which individual document instances can be validated. All of the popular XML parsers, whether they implement the SAX API or the DOM API, provide XML Schema based validation. You can specify the schema to which an XML document claims conformance within the XML document itself, but you can also ask a parser to validate an arbitrary XML document against an arbitrary schema.

SQL provides a powerful and very useful query facility for finding, transforming, and retrieving structured data from relational databases, so it s natural to seek a similar query capability for finding, transforming, and retrieving structured data from XML documents. The earliest efforts to define a query and transformation capability were embodied in a pair of specifications eXtensible Stylesheet Language Transformation (XSLT) and XML Path Language (XPath). Like XML itself, these specifications have their roots in document processing XSLT focuses on transforming an XML document, as shown in Figure 25-8. A stylesheet governs the transformation, selecting which elements of the input XML document are to be transformed and dictating how they are modified and combined with other elements to produce the output XML document. One popular use for XSLT is to transform a single, generic version of a web page into various forms that are appropriate for rendering on different screen sizes and display devices. Within the XSLT language, it is often necessary to select individual elements or groups of elements to be transformed, or to navigate through the element hierarchy to specify data to be combined from parent and child elements. XPath originally emerged as a part of the XSLT language for element selection and navigation. It quickly became apparent that XPath was useful for other applications as well, and the specification was split out of XSLT to stand on its own. In the early days of XML, XPath was the de facto query capability for XML documents. More recently, industry attention has focused on some of the deficiencies of XPath as a full query language. A W3C working group was formed to specify a query facility under the working name XML Query, or XQuery. As the specification passed through
