Course Overview
Master the essentials of XML, Java
XML APIs and XML Transformations.
Explore fundamentals of XML
including document structure, DTDs
and XML Schema. Explore a detailed
hands-on examination of the two main
parser JAXP APIs - SAX 2.0 and DOM
2.0 and JAXP's XML transformations
capabilities (XSLT 2.0, XSL-FO and
XPath 2.0)
Course Style
This course provides a basic
introduction to XML and the Java XML APIs. The course is a balanced mixture of
theory and practical labs designed to take students from the basic fundamentals
of XML right through to mastery of the standard Java XML APIs. The course starts
with the fundamentals of XML including document structure, DTDs and XML Schema.
It then moves on to the basic relationship between Java and XML, including
generating XML from Java and the mapping between Java and XML objects. Finally,
students are taken through a detailed and hands-on examination of the two main
JAXP APIs - SAX 2.0 and DOM 2.0. The course concludes with a look at some Java
and XML related topics.
