Digester Package org.apache.commons.digester Description - V1.8 (해석중)

Introduction

In many application environments that deal with XML-formatted data, it is useful to be able to process an XML document in an "event driven" manner, where particular Java objects are created (or methods of existing objects are invoked) when particular patterns of nested XML elements have been recognized. Developers familiar with the Simple API for XML Parsing (SAX) approach to processing XML documents will recognize that the Digester provides a higher level, more developer-friendly interface to SAX events, because most of the details of navigating the XML element hierarchy are hidden -- allowing the developer to focus on the processing to be performed.
