Lesson 9 - Working with XML files using the DOM approach in Java
In the previous lesson, Reading XML via the SAX approach in Java, we learned to read XML files using the SAX approach. We wrote a file, element by element, and read them the same way as well. In today's tutorial, we're going to look at another way to work with XML files, which is called DOM.
DOM (Document Object Model) is an object-oriented API for working with XML files. It's an alternative approach that has certain advantages and certain disadvantages. Meaning that DOM doesn't replace SAX, and we usually decide which of the techniques to use for working with XML files based on our applications' requirements.
DOM sees an XML file as an object, moreover, a tree structure. Elements are no longer seen one after other but nested into each other logically. We work with individual nodes and ask for their sub-elements. This greatly simplifies our work and we also gain the ability to easily edit XML files by adding
