Table 11.1 summarizes some of the features of the three most popular XML processing models. Conclusion In this chapter, we discussed the basic structure and concepts of XML instance documents. It is important to understand these structure and concepts because XML forms the basis of WSDL, SOAP, and UDDI. Some of the concepts we touched upon are XSD schemas (which describe the structure and grammar of a particular type of XML instance document) and namespaces. Namespaces are used to avoid the collision of names in different business domains and to extend a tag s name vocabulary across different domains. Within the context of namespaces, we discussed the use of include and import elements, which allow us to include the definition of a set of tags defined in another schema. A very important practical side of XML use in Web Services is the exchange of data between service provider and service consumer through the use of XML instance documents. In this context, both the service provider application and the service consumer application must be able to parse, process, edit, and create XML instance documents. A large part of this chapter was devoted to describing the various processing/parsing models available to the developer of Web Services. The various parsing/processing models we discussed include SAX, StAX, DOM, XML data-binding model (JAXB), and XSLT transformations. We also discussed the conditions under which each of these models should be employed. In the next chapter you will begin to see direct application of XML. You learn about SOAP, which is one of the four standards that constitute Web Services. SOAP is based on XML and it defines a common message format for exchanging messages between the service provider and service consumer.

Simple Object Access Protocol (SOAP) is an XML-based messaging specification. It describes a message format and a set of serialization rules for data types, including structured types and arrays. This XMLbased information can be used for exchanging structured and typed information between peers in a decentralized, distributed environment. In addition, SOAP describes the ways in which SOAP messages may be transported to realize various usage scenarios. In particular, it describes how to use Hypertext Transfer Protocol (HTTP) as a transport for such messages. SOAP messages are essentially service requests sent to some end point on a network. The end point may be implemented in a number of different ways, including an RPC server, a Java servlet, a Component Object Model (COM) object, and a Perl script, which may be running on any platform. A SOAP message is fundamentally a one-way transmission between SOAP nodes, from a SOAP sender to a SOAP receiver. In other words, a SOAP message may pass through a number of intermediaries as it travels from the initial sender to the ultimate recipient. SOAP Messages The basic structure of a SOAP message is depicted in Figure 12.1. The top element of a SOAP message is the Envelope element, with an optional Header element and a mandatory Body element as the children elements. If a Header element exists, it must be the first child of the Envelope element. The Envelope element identifies the XML document as being a SOAP message and therefore must be the root element of the message. The Body element contains the actual data (payload) to be transmitted. The Header element is an extension hook that can be used to extend SOAP in arbitrary ways. Envelope and its two children
