by Valentina Birsan, Tim DeBoer, Gary Flood, Jane Fung, James Hunter, Christina Lau, Yen Lu, Ellen McKay, Dr. Gili Mendel, Peter Walker, Joe Winchester, Colin Yu
5 Introduction to XML Development The Extensible Markup Language ( XML) has been around long enough now that the majority of users are probably familiar with it. It is a platform-independent language that can be used to transmit both information and data. Rational Application Developer provides a complete set of visual tools to help you develop XML applications. XML is so versatile that it can be used any-where— you can use it in a Web project, with a relational database, with an EJB, etc. In this chapter, you learn how to create XML and use it in your applications. Rational Application Developer provides a number of XML authoring tools. Figure 5- 1 shows the list of available XML wizards. To create an XML file, you use the XML File Creation wizard and the XML editor. When you use the XML File Creation wizard, you will be asked whether you want to create the XML file from a Document Type Definition ( DTD) file, from an XML Schema ( XSD) file, or from scratch, as shown in Figure 5- 2. Both the DTD and XSD files define the vocabularies and describe the proper syntax of building an XML document. 161
