This course requires that students meet the following prerequisites:

• A moderate degree of Web development experience using HTML and XML.
• A moderate degree of experience scripting with Visual Basic for Applications, VBScript, or JavaScript.
• Some prior experience using COM objects, Active Server Pages (ASP pages), and either Visual Basic or Microsoft Visual C++®.
• Taking one or more of the following courses will help the students meet the prerequisites and get more out of the course:
• Course 1905, Building XML-Based Web Applications
• Course 1013, Mastering Microsoft Visual Basic 6 Development
• Course 1017, Mastering Web Application Development Using Microsoft Visual InterDev 6

After completing this course, students will be able to define XML Path Language (XPath) expressions to locate and filter the content of an XML document; define XSLT style sheets to transform XML documents at the Web browser and Web server; create and change XML structure by using XSLT; use XSLT to merge different XML documents and generate cross-references between them; and create a Visual Basic application that uses the Simple API for XML (SAX) to access large XML documents
