Oracle 10g: XML Fundamentals


What you will learn:

This class is applicable to Oracle9i and Oracle Database 10g users. This class does not cover XML Publisher

This course introduces students to the basics of XML. The students learn how to create an XML document and format it using XML Stylesheet Language for transformations (XSL). The students validate XML documents using Document Type Definition (DTD) and XML Schema. The course discusses XPath expressions and how to use XPath expressions in XSL to select parts of an XML document to be transformed. XML Namespaces are used to apply uniqueness to elements, and parsing XML documents is done using Document Object Model (DOM). The Simple API for XML (SAX) is also discussed as a technique to parse XML documents. In addition, the students are introduced to the support for XML offered in various Oracle products, such as, the Oracle Database, Oracle XML DB, Oracle XML Developer's Kit, Oracle JDeveloper, and Oracle XSQL pages. The students learn how to format, query, validate, and store their XML documents using Oracle products.
