XML is used in many systems for integrating within an organization or across them. This course will teach you how to read and write documents using the various APIs available in Java, as well as cover document querying and validations.
XML is a standard for storing data and integrating systems within and between organizations. In this course, Java SE: XML Processing Fundamentals, you'll learn the basics of reading and writing XML documents using all the various APIs available. First, you'll discover the tradeoffs between each - understanding which options offer better memory efficiency versus processing control. Next, you'll learn that systems working together need to ensure the data being passed is valid. Finally, you'll explore how to create XML schemas to provide documentation of allowable elements and use them to perform validations while reading documents. By the end of this course, you'll have a solid understanding how to query into documents to efficiently find subsets of data often needed when working with XML.
Course Overview Hello, my name is Mike Nolan, and welcome to my course Java SE: XML Processing Fundamentals. I am a solution architect with US Foods, and have been working with Java technologies for more than 15 years. XML is the specification defining rules for structuring documents and exchanging data in a descriptive manner. It is used in many systems for integrating within an organization or across them. It provides a means for defining validity rules of these structures and supporting the ability to check that documents conform to these at runtime. With Java being an enterprise class programming language used for implementing systems, knowing its vast ecosystem of XML processing capabilities is important. There are many means for reading and writing documents, with each having a particular set of trade-offs. By the end of this course, you will know how to use each of the APIs for reading and writing documents. Some allow you to process at a very low level pulling specific elements of a document while others can bind a complete document in a very concise manner. You'll also understand the XML schema specification and how to leverage it in Java to perform document validations. Additionally, we will cover the basic of XPath, a query language used for filtering XML documents to help simplify your coding. I hope you'll join me in this journey to learn XML processing and Java SE: XML Processing Fundamentals course at Pluralsight.
