XML and Text Processing with OmniMark^®

Overview

There are two fundamental programming problems associated with XML: the interpretation and transformation of XML data streams, sometimes called "down-translation" and the interpretation and transformation of non-XML data to create XML data streams, sometimes called "up-translation".

This course covers both up and down translation and includes hands-on development.

Course Objectives

On completion of this course, delegates will be able to:

• Initiate event-driven XML processing
• Employ OmniMark's comprehensive XML context management features
• Analyse and extract information using OmniMark's sophisticated pattern matching facility
• Apply streaming technology to information transformation applications
• Engineer OmniMark applications to maximize efficiency
• Reorder information efficiently using OmniMark's patented referent technology

Course Length

Five days

Prerequisites

• Proficiency in a block-structured programming language (not necessarily object oriented) in addition to knowledge of XML syntax
• Knowledge of Internet technology, particularly HTML coding
• An understanding of the underlying concepts of XML is expected and can be gained by attending our 1-day "Introduction to XML Technologies Workshop".
• Knowledge of rule or event-based programming and regular expressions is also useful, but not required
