NewEventLinkTransformer
public class NewEventLinkTransformer extends AbstractCopletTransformer (Code)
This transformer is used to replace links (URIs) from elements like <a href="URI"> or <form action="URI"> with portal event uris. Therefore the transformer searches for <eventlink> elements replaces the URI form the attribute which is specified within an attribute called "attribute" and renames the element as specified within an attribute called "element". Example:

 <root xmlns:ev="http://apache.org/cocoon/portal/eventlink/1.0">
 <ev:eventlink href="http://eventlinkexample" element="a" attribute="href">linktext</ev:eventlink>
 </root>
will be replaced with something like:

 <root>
 <a href="portal?cocoon-portal-event=8">linktext</a>
 </root>
The transformer will create two CopletLinkEvents and insert corresponding links to them to the XML instead of "http://eventlinkexample". If such a link is pressed the corresponding CopletLinkEvent is sent to the Subscribers to be handled.
Please see also the documentation of superclass AbstractCopletTransformer for how the coplet instance data are acquired.
