public class WriteDOMSessionTransformer

extends AbstractTransformer

Make a DOM object from SAX events and write it to the session. Usage in sitemap: <map:transform type="writeDOMsession"> <map:parameter name="dom-name" value="content"/> <map:parameter name="dom-root-element" value="companies"/> </map:transform> Where: dom-name is the name for the DOM object in the session dom-root-element is the trigger that will be the root element of the DOM
