Examples of org.apache.commons.digester.Digester

org.apache.commons.digester.Digester

A Digester processes an XML input stream by matching a series of element nesting patterns to execute Rules that have been added prior to the start of parsing. This package was inspired by the XmlMapper class that was part of Tomcat 3.0 and 3.1, but is organized somewhat differently.

See the Digester Developer Guide for more information.

IMPLEMENTATION NOTE - A single Digester instance may only be used within the context of a single thread at a time, and a call to parse() must be completed before another can be initiated even from the same thread.

IMPLEMENTATION NOTE - A bug in Xerces 2.0.2 prevents the support of XML schema. You need Xerces 2.1/2.3 and up to make this class working with XML schema
