Examples of org.apache.tomcat.util.xml.XmlAction

org.apache.tomcat.util.xml.XmlAction
Each rule in Xml Mapper can invoke certain actions. An action implementation will be notified for each matching rule on start and end of the tag that matches. After all end actions are called, a special cleanup call will allow actions to remove temporary data.
