Unlike the SAX approach, there is no need in DOM to write a content handler and callback methods. However the DOM approach requires you to understand the organization of the document tree. In fact, if you use DOM to access data, you create a parser that builds a tree, and then you use DOM methods to navigate to the appropriate object in the tree that contains the data you need. So an understanding of the tree's organization is a requirement. Compare this to JAXB, where you have direct access to unmarshalled XML data through objects in the content tree. As in DOM-based processing, JAXB allows access to data in non-sequential order, but it doesn't force an application to navigate through a tree to access the data. In addition, with all the creating and appending of objects that represent the nodes of the tree, the DOM approach can be tedious.
