The DOMParser is probably the most commonly used Java object for reading and validating XML documents. The DOMParser reads the XML and (depending on the parser initialization) will validate the XML against an XML schema. If the XML is valid, the DOMParser will return a Document (DOM) object, which represents the XML as a tree structure. The XML can be processed by walking this tree. An example of how the DOMParser can be applied to processing arithmetic expressions in XML format is discussed on a companion web page.
