Objectives of the training
This training course aims to develop in-depth expertise in the use of XML in Java applications. It enables participants to acquire the skills needed to manipulate XML formats via the DOM, SAX, and XSLT APIs, while understanding their differences and impact on performance. It also covers alternatives such as STAX, JDOM, and DOM4J for more tailored use depending on project requirements.Targeted audience
Java developersPrerequisite
Basic knowledge of XML structure and syntax. Basic knowledge of XPath and XML schemas. Know how to create and manipulate classes, objects, interfaces, and exceptions. (Object-oriented training, not necessarily Java) Knowledge of collections (List, Map, Set) and iterators. Proficiency in input/output (I/O), particularly reading/writing text and binary files.Trainers
